发明名称 System and method for reducing dynamic range of modulated signals without increasing out-of-band power
摘要 A signal processing system and method which operates to reduce a crest factor of an input signal without increasing the signal bandwidth. An embodiment provides for identifying peaks in the input signal which exceed a clipping threshold. The characteristics of such identified peaks can then be used to determine a clipping wavelet which can be added to a waveform of the input signal so that the peak will not exceed the clipping threshold. The addition of the wavelet is a linear operation, and the clipping wavelet is limited in terms of bandwidth and time, such that it does not increase the out-of-band spectral content of the input signal.
