Patent ID: 7236052

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; and a signal processing subsystem receiving and processing said predistorted signal and producing a system output signal, wherein said 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 characteristics of said system output signal and said input signal, wherein said deliberate predistortion includes magnitude distortions capable of adjusting a magnitude of said input signal.
