Patent attributes
A signal clipping processing method and a device, the method including performing peak detection on an input signal, so as to obtain amplitude information, phase information, and location information of a peak signal of the input signal; obtaining, according to amplitude information and phase information of each peak signal, a peak forming factor corresponding to each peak signal, and separately outputting, according to location information of each peak signal, a corresponding cancellation pulse sequence; and calculating a sum of products of peak forming factors corresponding to all peak signals and cancellation pulse sequences corresponding to all the peak signals, so as to obtain a clipping noise, and using a difference between the input signal and the clipping noise as a signal obtained after clipping processing.
