The embodiment of the invention provides a clipping method and device. The clipper is a base station, the base station includes the baseband unit BBU and the remote radio frequency unit RRU; the BBU includes a first processor, which includes a second processor; the first processor is used to cut the input N carrier after the path is chopping and outputs the N carrier wave after the first stage clipping; the second processor is used for the description. After the first level clipping, the N carrier is combined to cut the wave and output the N carrier of the second stage clipping. The N is an integer greater than or equal to 2. In the above scheme, the base station can cut the wave in BBU and RRU respectively, so that the base station can flexibly select the baseband single board or baseband chip to deploy the first stage clipping according to the processing capability of the different baseband single board or baseband chip, so as to improve the expansibility of the base station.
