Abstract: PAPR suppression includes a first clipping module and a second clipping module. The second clipping module outputs, to the first clipping module, a to-be-clipped signal that satisfies an input condition of the first clipping module, where the input condition includes a peak distribution feature of an input signal. The first clipping module performs first clipping processing on the to-be-clipped signal to obtain a first clipped signal. PAPR suppression is performed based on collaboration between the two clipping modules.
