Patent ID: 7068101

Claim:
A system for processing an input signal, the system comprising: an adaptive predistortion subsystem for receiving said input signal and for producing a predistorted signal by applying a deliberate predistortion to said input signal, wherein said deliberate predistortion includes magnitude distortions which adjust a magnitude of said input signal; and a signal processing subsystem receiving and processing said predistorted signal and producing a system output signal, wherein said adaptive predistortion subsystem distorts said Input signal to compensate for distortions in said system output signal; said signal processing subsystem decomposes said predistorted signal into separate components, each of said separate components being processed separately; said processing subsystem combines said components after processing to produce said system output signal; and said deliberate predistortion applied to said input signal by said adaptive predistortion subsystem to produce said predistorted signal is adjusted based on said system output signal.
