Wireless Multiple Input Multiple Output (Mimo)transceiver System In High Speed Mobility And Methodthereof

Abstract: The disclosure relates to method and system for providing a MIMO transceiver in high speed mobility. The method includes dividing (302) transmission data into a plurality of transmit chains corresponding to an antenna. The method further includes generating (304) for the plurality of transmit chains, a Circularly Pulse Shaped Orthogonal Time Frequency Space (CPS-OTFS) time frequency signal based on a first primary parameter. Value of the first primary parameter is determined based on a first predefined algorithm. The method further includes converting (306) for the plurality of transmit chains, the CPSOTFS time frequency signal to a CPS-OTFS time domain signal based on at least one of a plurality of secondary parameters. A first plurality of N-point Inverse Fast Fourier Transform (IFFT) are employed on the CPS-OTFS time frequency signal. The first plurality corresponds to the number of sub-carriers and N corresponds to a set of time symbols.
