PEAK CLIPPING DEVICE AND MOBILE COMMUNICATION SYSTEM

摘要

Provided are a peak clipping device and a mobile communication system. The device includes: a peak value pulse generation module configured to generate a peak value pulse signal according to an input signal and send same to a peak value pulse weighting module; a weighted control signal generation module configured to generate a weight factor control signal according to an acquired modulation manner reference signal or frame synchronization signal and send same to the peak value pulse weighting module; a peak value pulse weighting module configured to weight peak value pulse signals received during different time periods respectively according to the received weight factor control signal and send the weighted peak value pulse signals to a first adder module; and a first adder module configured to overlap the weighted peak value pulse signals onto a peak value signal to be clipped to cancel the peak value signal to be clipped. The above technical solution provided by the present utility model realizes the effect that the peak clipping performance in the system can be improved.
