Output signal crest factor reducing method for e.g. asymmetric digital subscriber line system, involves characterizing partial corrector signals with preset frequencies to reduce crest factor of auxiliary signal by corrector parameters

摘要

The method involves generating an auxiliary signal (Y) from an input signal by filtering. Corrector parameters are calculated for the signal (Y) and characterize partial corrector signals with preset frequencies to reduce a crest factor of the signal (Y). A corrector signal is calculated depending on the parameters and transfer function of another filtering as a combination of another partial corrector signals with preset frequencies. An independent claim is also included for a device for reducing a crest factor of an output signal.
