Abstract: This application discloses a peak clipping method. The method includes: performing 1-out-of-N sampling on a first signal; then selecting, from a second signal obtained through the sampling, a noise point set of the second signal based on a second threshold; determining a candidate noise point set of the first signal based on the noise point set of the second signal; selecting a noise point set of the first signal from the candidate noise point set of the first signal based on a first threshold; determining a peak clipping coefficient based on the noise point set of the first signal; clipping the first signal based on the peak clipping coefficient; and finally outputting a clipped first signal. In this method, fewer sample points are used for peak clipping, reducing storage space. This application further discloses a signal processing apparatus and a network device that can implement the foregoing method.
