ABSTRACT:
Circuits for reducing the signal peaks in telecommunications signals are described. The circuits and methods are preferably adapted for reducing the peak to average power ratio of non-constant envelope modulation signals. In one example the circuit includes a band-limiting filter for limiting the bandwidth of a data bearing signal and a predictive filter for predicting peaks in the data bearing signal at the output of the pulse-shaping filter. The circuit also includes a clipping processor for generating a compensation signal in response to one or more signal peaks predicted by the predictive filter and a signal combining device for applying the compensation signal to the data bearing signal prior to amplification of the data bearing signal.
