Patent ID: 8594232

Claim:
A system for distortion compensation embodied in a transceiver, said system comprising a predistorter operably disposed between a digital transmitter and a power amplifier; a post-distorter operably disposed between a receiver amplifier and a digital receiver; said system being configurable to operate in a configuration mode with said transmitter and receiver active; and said post-distorter adapted to compensate for nonlinearities in the receiver amplifier and, in configuration mode, produce post-distorted in-phase and quadrature-phase output signals and communicate such signals to the predistorter by filtering amplified signals from the receiver amplifier using a low pass filter, converting the filtered signals to digital signals using an analog to digital converter, producing the post-distorted in-phase and quadrature-phase output signals based upon the digital signals, and communicating the post-distorted in-phase and quadrature-phase output signals to the predistorter; and said predistorter adapted to compensate for nonlinearities in the power amplifier by linearizing output from the digital transmitter.
