Peak clipping method, signal processing device and network equipment

The invention discloses a peak clipping method which comprises the following steps: after 1-N sampling is carried out on a first signal, selecting a noisy point set of a second signal from the sampled second signal according to a second threshold, and then determining a candidate noisy point set of the first signal according to the noisy point set of the second signal, and selecting a noisy point set of the first signal from the candidate noisy point set of the first signal according to a first threshold, then determining a peak clipping coefficient according to the noisy point set of the first signal, clipping the first signal according to the peak clipping coefficient, and finally outputting the clipped first signal. According to the method, peak clipping is carried out by adopting fewer sample point numbers, and the storage space can be saved. The invention further discloses a signal processing device and network equipment capable of realizing the method. 本申请公开一种削峰方法包括：对第一信号进行N抽1采样后，根据第二门限从采样得到的第二信号中选择第二信号
