Systems and methods for reducing signal distortion in wireless communication

摘要

System and methods are provided for reducing signal distortion in wireless communication. An example system includes: an up-converter configured to generate a radio frequency signal based at least in part on a baseband signal for wireless communication and an oscillation signal; an amplifier configured to amplify the radio frequency signal and generate a transmission signal, the transmission signal including a first counter-intermodulation component associated with the up-converter and a second counter-intermodulation associated with the amplifier; and a signal generator configured to output a distortion-cancellation signal to the up-converter to reduce signal distortion associated with the first counter-intermodulation component and the second counter-intermodulation component.
