[001]The present disclosure relates to the field of communication systems. More particularly, the present disclosure relates to a system and method with multiple modulation schemes for enabling multimedia (voice or audio and video) communication. BACKGROUND [002]Background description includes information that can be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. [003] Modulation is a process by which audio, video, picture or textual information can be added to an electrical or optical carrier signal to be transmitted over a telecommunication or electronic medium. The modulation enables the transmission of information about an electrical signal to a receiving device, which demodulates the signal to extract the mixed information. The modulation is mainly used in telecommunication technologies that require the transmission of data via electrical signals. It is considered as backbone of data communication because it allows the use of electrical and optical signals as information carriers. The modulation is achieved by changing the periodic waveform or the carrier. This includes carrying amplitude, frequency and phase. Most of radio communication systems use frequency modulation (FM) or amplitude modulation (AM). A modem is a common example or implementation of a modulation technique in which the data is modulated with electrical signals and transmitted over telephone lines, and the modem performs both modulation and demodulation. It will be demodulated later to receive the data. Many factors affect how exactly the modulated or extracted information replicates the original input information. Electromagnetic interference can affect the signals and make it impossible to extract the original signal. Demodulators typically include multiple stages of amplification and filtering to eliminate interference. [004] For example, a computer audio modem allows a computer to connect to another computer or data network via a standard analog telephone line by using the data signal to modulate an analog audio tone. A modem on the other end demodulates the audio signal to restore the data stream. A cable modem uses network data to modulate the cable service provider's signal. [005] There are two types of modulationi.e. analog modulation and digital modulation, and these types are based on a type of signal to be modulated. Main aim of analog modulation is to transfer an analog baseband signal, for example an audio signal or TV signal over an analog band pass channel at a different frequency. In analog modulation, a continuously varying sine wave can be used as a carrier wave modulating a message signal or data signal. Three parameters can be changed here to achieve a modulation, and those parameters are amplitude, frequency and phase. For better quality and efficient communication, the digital modulation technique can be used. The main purpose of digital modulation is to transfer digital data over a set of channels i.e., for example over PSTN (Public Switched Telephone Network). The main advantages of digital modulation over analog modulation are allowable power, available bandwidth and high immunity to interference. In digital modulation, a message signal is converted from an analog to a digital message and then modulated using a carrier wave. The carrier wave can be sampled or turned on and off to generate pulses so that the signal is modulated. Similar to the analog modulation, the parameters such as amplitude, frequency and phase change of the carrier wave determine the type of digital modulation. The types of digital modulation schemes can be ASK or Amplitude shift Keying, FSK or Frequency shift keying, PSK or Phase shift keying etc. Further, the purpose of digital modulation is to transfer digital data over a set of channels, for example over Public Switched Telephone Network (PSTN). [006] In mobile communication systems, adaptive modulation is utilized. Adaptive modulation is the ability to modify modulation schemes based on characteristics of the transmission channel and/or the throughput requirements of the user. For example, in EDGE mobile communication system, this technique is termed as link adaptation. Most of existing voice and/or mobile communication systems (especially voice over IP (VoIP) communication systems) utilize adaptive modulation schemes that may work with ARQ(Automatic Repeat Request) and HARQ (Hybrid Automatic Repeat Request). In VoIP applications, to ensure good quality speech or any other information at receiver side, one-way transmission delay may not exceed 150 ms. By implementing ARQ and HARQ for reliable transmission in VoIP applications, additional delays and interference may be created in data (voice) communication. Although, HARQ can be considered as a better candidate for VoIP applications due to faster feedback and retransmission gain, its implementation may not be always desirable or even possible. The reason is HARQ may possess a larger signalling overhead and may not suitable for real time applications (during voice calls, video calls etc. via data packets).Many of existing adaptive modulation and coding schemes (AMCS) in combination with ARQ can be appropriate for transmission control protocol(TCP) applications. The time that can be taken to switch between modulation schemes as per channel condition may increase overhead for internet protocol (IP) telephonic applications. Hence, most of the existing AMCS may not be suitable for the real time applications like VoIP. Further, VoIP communication systems may be affected with decrement in throughput of the entire system, data transfer rate and with increase in packet loss rate. [007] Therefore, there is a need in the art to provide a reliable and adaptive modulation system and method for enabling voice/data communication with high data rate and with reduced retransmissions. Further, there is a need in the art to provide the system and the method to reduce switching or modulation selection time between modulation schemes to reduce packet loss rate and to increase throughput during data transfer.

[0066] FIG. 1 illustrates an exemplary block diagram representation of a system for providing real-time multimedia communication over at least a communication channel, in accordance with an embodiment of the present disclosure. [0067] According to an embodiment, the system 100 can include one or more processor(s) 102. The one or more processor(s) 102 can be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processor(s) 102 are configured to fetch and execute computer-readable instructions stored in a memory 104 of the system 100. The memory 104 can store one or more computer-readable instructions or routines, which can be fetched and executed to create or share the data units over a network service. The memory 104 can include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like. [0068] Various components /units of the proposed system 100 can be implemented as a combination of hardware and programming (for example, programmable instructions) to implement their one or more functionalities as elaborated further themselves or using processors 102. In examples described herein, such combinations of hardware and programming can be implemented in several different ways. For example, the programming for the units can be processor executable instructions stored on a non-transitory machine-readable storage medium and the hardware for units can include a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine-readable storage medium can store instructions that, when executed by the processing resource, implements the various units. In such examples, the system 100 can include the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium can be separate but accessible to the system 100 and the processing resource. In other examples, the units can be implemented by electronic circuitry. A database 114 can include data that is either stored or generated as a result of functionalities implemented by any of the other components /units of the proposed system 100. 14 [0069] In an embodiment, the system 100can include: a transceiver 108 that can be configured to transmit a set of analog signals corresponding to an input user data over the communication channel; an analog-to-digital converter (ADC) 110 that can be operatively coupled to the transceiver 108 and can be configured to convert the set of analog signals to a corresponding set of digital signals; at least one compressor-decompressor (codec) unit 112 that can be operatively coupled to the ADC, the at least one codec unit can be configured to compress the set of digital signals; and a control unit 106 that can be operatively coupled to the codec unit 112. [0070] In an embodiment, the control unit 106 can include one or more processors 102 and memory 104 that can be coupled with the one or more processors 102. The memory 104 can be storing computer implemented instructions which when executed by the one or more processors 102 to: determine signal-to-noise ratio (SNR) of the communication channel based on compression of the set of digital signals; and sense noise parameters of the communication channel to transmit the determined SNR as a feedback to the transceiver 108. [0071] In an embodiment, the control unit 106 can be configured to select a modulation scheme based on the sensed noise parameters, wherein the control unit can be configured to select quadrature phase shift keying (QPSK) modulation scheme with a coding rate of ½ when the determined SNR is less than a predetermined threshold value that can be stored in the database 114 that can be operatively coupled to the control unit 106, and wherein the control unit 106 can be configured to select quadrature amplitude modulation (QAM) scheme with a coding rate of ¾ such that a threshold bit error rate (BER) range is maintained. [0072] In an embodiment, the control unit 106 can be configured to compare the determined SNR with the predetermined threshold SNR value. [0073] In an embodiment, the transceiver 108 can be configured to transmit, based on the selected modulation scheme corresponding to the determined SNR, the set of analog signals and provide reliable voice communication among the transceiver 108 and a set of other transceivers with enhanced data quality. [0074] In an embodiment, the set of analog signals can include data or information associated with any or a combination of voice signals and video signals. [0075] In an embodiment, the codec unit 112 can be configured to implement G.711 pulse code modulation (PCM) standard. The communication channel can be time varying wireless channel 15 [0076] Adaptive modulation and coding selection scheme(AMCS) is one of the main processes that can be used to improve throughput of a time varying wireless channel. It is designed to track the quality of the channel by adapting channel throughput to an actual channel state and maintain a predicted BER. When the channel state is poor, signal constellation size can be reduced in order to improve fidelity, and the SNR can be reduced to make the transmission more robust. Also during low fading, i.e., high SNR, the signal constellation size can be increased in order to allow higher data rate modulation method, to provide lower probability of error. This improves the instantaneous SNR. The performance of AMC can be better with accurate channel state information (CSI) at the transmitter. One of the techniques used in AMC is based on the SNR ranges at the receiver for channel quality information (CQI). The transmitter selects a particular modulation and coding method for further communication, depending on the estimate of the channel state. Threshold value for SNR can be fixed in such a way that it decides the required BER. [0077] To ensure an accurate adaptation, a feedback mechanism can be considered in a channel, which is free from all types of errors. The associated CSI is sent back to the transmitter, which then adapts its transmission rate and the particular modulation scheme. By transmitting with the adapted modulation scheme, it guarantees that the required BER .This helps the system to transmit data with a high spectral efficiency, when the SNR is high and decrease the spectral efficiency as the SNR reduces. [0078] Adaptive MCS can work pretty well with ARQ packets. However, for real time applications like VoIP, there is no retransmission packet available for missed, dropped, or corrupted packet, which affects in the degradation of the voice quality. Therefore, adaptive coding and modulation may not suit for real time applications like VoIP. [0079] In an exemplary embodiment, the target or threshold BER that is employed for adaptive modulation scheme can be performed considering the error rate under a target limit say 0.01 or 0.001, maintaining a fixed quality level of service with regards to error probability. The target BER technique works with the principle that the system works with the lowest modulation and coding scheme, namely QPSK modulation with coding rate 1/2, until the signal-to-noise ratio changes, then the system switches on higher modulation transmission schemes to produce a much better spectral efficiency while maintaining the desired or threshold BER target. If input data streams are transmitted using 64 QAM with a coding rate of ¾, the throughput can be maximized but there can be lower BER performance. Therefore, by compromising the throughput performance to some extent, the modulation and 16 coding rate schemes can be changed to keep the error rate below our desired BER level. High throughput exhibits high BER value and that is a trade-off. [0080] In an embodiment, the one-way transmission delay of a VoIP application must not exceed 150 ms to ensure a good quality speech at a receiver side. The ARQ and HARQ used for the reliable retransmission mechanism can create additional delay on the VoIP packets. Even though, HARQ can be considered as a better candidate for VoIP applications due to a faster feedback and the retransmission gain, its usage may not always desirable or even possible. HARQ possesses a larger signalling overhead and not suite for real time applications. The existing or prior art adaptive MCS in combination with ARQ best suits for TCP applications. The time taken to switch between the modulation as per the channel condition increases the overhead for the IP telephony application. So the prior art AMCS may not suit for real time application like VoIP. The time sensitive VoIP application may require a modified MCS, which delivers more packets, avoids retransmission, reduces the time for switching between the modulation schemes and thus reduces the packet loss rate. To achieve these parameters, an MCS algorithm is proposed in the system 100 that can switch between QPSK and QAM modulation schemes based on SNR feedback. [0081] In an exemplary embodiment, segregation of the channel as, low noise or good signal can be done based on the signal to noise ratio. The signal to noise ratio is the measure of amount of good signal to the amount of noise in the channels. The noisy channel has more noise signals than the good signals. The low noise channel has better signal than the noise signal. If the switching network indicates that the channel as noisy, then profile QPSK ½ can be applied for modulating the packets otherwise the packet can be modulated using the profile 16 QAM ¾. [0082] It would be appreciated that although the proposed system 100 has been elaborated as above to include all the main units, it is conceivable that actual implementations are well within the scope of the present disclosure, which can include without any limitation, only a part of the proposed units or a combination of those or a division of those into sub-units in various combinations across multiple devices that can be operatively coupled with each other, including in the cloud. Further, the units can be configured in any sequence to achieve objectives elaborated. Also, it can be appreciated that proposed system 100 can be configured in a computing device or across a plurality of computing devices operatively connected with each other, wherein the computing devices can be any of a computer, a laptop, a smart phone, an Internet enabled mobile device and the like. Therefore, all possible 17 modifications, implementations and embodiments of where and how the proposed system 100 is configured are well within the scope of the present invention. [0083] FIG. 2 illustrates an exemplary flow diagram representation of a method for providing real-time multimedia communication over at least a communication channel, in accordance with an embodiment of the present disclosure. [0084] According to an embodiment, the method 200 can include at a step 202, transmitting, from a transceiver, a set of analog signals corresponding to an input user data over the communication channel. [0085] In an embodiment, the method 200 can include at a step 204, converting, using an analog-to-digital converter (ADC) operatively coupled to the transceiver, the set of analog signals to a corresponding set of digital signals; and at a step 206, compressing, using at least one compressor-decompressor (codec) unit, the set of digital signals. [0086] In an embodiment, the method 200 can include at a step 208, determining, by a processor operatively coupled to the codec unit, signal-to-noise ratio (SNR) of the communication channel based on compression of the set of digital signals. [0087] In an embodiment, the method 200 can further include at a step 210, sensing, by the processor, noise parameters of the communication channel to transmit the determined SNR as a feedback to the transceiver. [0088] In an embodiment, the method 200 can include at a step 212, selecting, by the processor, a modulation scheme based on the sensed noise parameters, wherein the processor is configured to select quadrature phase shift keying (QPSK) modulation scheme with a coding rate of ½ when the determined SNR is less than a predetermined threshold SNR value stored in a database operatively coupled to the processor, and wherein the processor is configured to select quadrature amplitude modulation (QAM) scheme with a coding rate of ¾ such that a threshold bit error rate (BER) range is maintained. [0089] In an embodiment, at the step 212 of selecting the modulation scheme, the processor can be configured to compare the determined SNR with the predetermined threshold SNR value. [0090] In an embodiment, at the step 212 of selecting the modulation scheme, the transceiver can be configured to transmit, based on the selected modulation scheme corresponding to the determined SNR, the set of analog signals and provide reliable voice communication among the transceiver and a receiver with enhanced data quality. The set of analog signals can include data associated with any or a combination of voice signals and video signals 18 [0091] In an embodiment, at the step 206 of compressing the set of digital signals, the at least one codec unit can be configured to implement G.711 pulse code modulation (PCM) standard. [0092] FIG. 3 illustrates an exemplary graphical representation of throughput performance of various digital modulation schemes, in accordance with an embodiment of the present disclosure. [0093] FIG. 4 illustrates an exemplary representation of voice application, in accordance with an embodiment of the present disclosure. [0094] FIG. 5A illustrates an exemplary graphical representation of throughput obtained with various MCS in noisy channel, in accordance with an embodiment of the present disclosure. [0095] FIG. 5B illustrates an exemplary graphical representation of throughput obtained with various MCS in low-noise channel, in accordance with an embodiment of the present disclosure. [0096] As shown in FIG. 3, throughput characteristics of different modulation schemes (QPSK, 16QAM, and 64QAM) with different coding rates are mentioned. [0097] As shown in FIGs. 4A & 4B, it can be concluded that 1/2 QPSK has better performance of BER but lesser throughput or spectral efficiency than other modulation schemes and coding rates. Hence, lower modulation & coding schemes can be preferable for high BER performance and higher modulations can be more desirable to get higher throughput. [0098] In an embodiment, an exemplary look-up table (Table-1) of CINR threshold for modulation and coding selection schemes (MCS) is given below.

A high CINR indicates that the carrier power is much greater than the noise power; and a low CINR indicates that the noise power is almost as high as the carrier power. Given the CINR of a device, the base station can consult a lookup table (Table-1) to decide which MCS can be assigned to a particular device. The lookup table lists a CINR threshold for every MCS profile. A MCS is assigned to a device, if its CINR is (approximately) greater than or equal to the threshold for that MCS and lower than the threshold for the next MCS. For example, if the threshold for profile QPSK 3/4is 14 dB and the threshold for 16QAM 1/2 is 17 dB, a mobile device with a CINR of 15 dB can use QPSK ¾; and if its CINR jumps to 19 dB, it can adapt and begin using 16QAM ½, as shown in the Table-1. [00100] In an adaptive system, the MCS can be switched for different SNR qualities with the intention to maintain the target BER of threshold 0.001. Here, the importance is given for restricting the BER and the throughput is compromised to maintain BER. The adaptive modulation and coding control for the SNR value is shown in the Table-1. [00101] In an embodiment, an exemplary table (Table-2) of profile index and adaptive modulation and coding control for corresponding SNR range is disclosed. 20 Table-2: AMC SNR Modulation Code Rate 1 6.4
