Crest-factor reduction method for signals e.g. in ADSL products

摘要

The method involves calculating a digital correction vector from the elements of the digital signal vectors (y1,y2,..yn). The elements are sampling values of the signal, which is presented by the digital signal vectors in the time domain. The digital correction vector and the digital signal vector are added and the corrected digital signal vector is output. Preferably, the elements of the digital correction vector are calculated from the biggest value and the smallest value of the digital signal vector.
