Power amplifier digital predistortion system for concurrent dual band inputs

摘要

A method and system for pre-distorting dual band signals to compensate for distortion of a non-linear power amplifier in a radio transmitter are disclosed. According to one embodiment, a first signal in a first frequency band and a second signal in a second frequency band are pre-distorted according to first and second pre-distortion function, respectively, the first and second pre-distortion functions being the dual of one another.
