Abstract:
1. A method of processing an input signal to produce a system output signal, the method comprising: a) receiving said input signal; b) applying a deliberate predistortion to said input signal to result in a predistorted signal; c) decomposing said predistorted signal into at least two component signals; d) combining said at least two component signals to produce said system output signal; e) adjusting said deliberate predistortion based on said system output signal f) concurrent with steps b)-e), executing the following steps: f1) delaying a replica of said input signal; f2) diverting a diverted replica of said system output signal to a feedback path; f3) processing said diverted replica to produce a corrected version of said diverted replica; and f4) determining said deliberate predistortion using said corrected version and said replica of said input signal.
