Patent ID: 7026871

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