A Modulator, A Method For Modulating An Information Signal, A Transmitter In A Cellular Telephone And A Demodulator


Updated 11 months ago

Abstract

The present invention relates to a modulator comprising: a first mixer configured to receive and modulate an inphase carrier signal with an inphase information signal to generate a first modulated component; a second mixer configured to receive and modulate a quadrature carrier signal with a quadrature information signal to generate a second modulated component; a third mixer configured to receive and modulate the inphase carrier signal with the quadrature information signal to generate a third modul~ted component, wherein the third modulated components has a signal inversion; a fourth mixer configured to receive and modulate the quadrature carrier signal with the inphase information signal to generata a fourth modulated component; a first summer coupled to the first and fourth mixers, the first summer configured to receive and combine the first and fourth modulated components to generate an inphase modulated component; and a second summer coupled to the second and third mixers, the second summer configured to receive and combine the second and third modulated components to generate a quadrature modulated component.The present invention also relates to a method for modulating an information signal, a transmitter in a cellular telephone and a demodulator.
