Patent ID: 7034613

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; a signal processing subsystem receiving and processing said predistorted signal and producing a system output signal; a feedback signal processing subsystem for receiving and processing a feedback signal derived from said system output signal; and a delay subsystem for providing a delay to a replica of said input signal to produce a delayed signal, said delayed signal being used by said adaptive predistortion subsystem and said feedback processing subsystem, 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; an output of said feedback processing subsystem being used by said adaptive predistortion subsystem; 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; said predistortion subsystem is controlled by a preprogrammed control device.
