Abstract:
Embodiments of the present disclosure provide a clipping method and an apparatus. The clipping apparatus is a base station, and the base station includes a baseband unit (BBU) and a remote radio unit (RRU). The BBU includes a first processor, and the RRU includes a second processor. The first processor is configured to: perform clipping after combining N input carriers, and output N carriers obtained after a first level of clipping; and the second processor is configured to: perform clipping after combining the N carriers obtained after the first level of clipping, and output N carriers obtained after a second level of clipping, where N is an integer greater than or equal to 2. The base station separately performs clipping at the BBU and the RRU, so that the base station can flexibly select, a baseband processing board or a baseband chip to deploy the first level of clipping.

Claim (Index 2):
The base station according to  claim 1 , wherein to perform clipping after combining N input carriers, the processor is configured to:\n upsample each carrier of the N input carriers, wherein a sampling rate used in the upsampling is N times an original sampling rate of each carrier; combine N upsampled carriers, extract a noise from a combined signal, and split the noise to obtain a noise of each carrier; downsample the noise of each carrier, wherein a sampling rate used in the downsampling is the same as the original sampling rate of each carrier; and delay each carrier of the N input carriers, and cancel a downsampled noise of each carrier from each delayed carrier, to obtain each carrier obtained after the first level of clipping, wherein during noise cancellation, a delay of each delayed carrier is the same as a delay of the downsampled noise of each carrier.
