METHOD AND SYSTEM FOR GENERATING ODD ORDER PREDISTORTIONS FOR A POWER AMPLIFIER RECEIVING CONCURRENT DUAL BAND INPUTS

摘要

A method and system for pre-distorting a dual band signal to compensate for distortion of a non-linear power amplifier in a radio transmitter are disclosed. In one embodiment, a first and second signal of the dual band signal are up-sampled at a sampling rate that is based at least in part on the bandwidth of at least one of the first and second signals and based at least in part on an intermediate frequency by which the first and second signal are tuned before pre-distortion of the tuned signals.
