Abstract
The disclosure discloses a method and device for performing peak clipping to multiple carrier waves, the method includes: according to carrier wave number of configured multiple carrier waves, signal bandwidth and occupied bandwidth of each carrier wave, obtaining total signal bandwidth and total occupied bandwidth of the corresponding carrier waves; according to the total signal bandwidth and the total occupied bandwidth of the multiple carrier waves, generating a digital filter with set order, and obtaining filter coefficient of the digital filter; taking the filter coefficient as a peak clipping coefficient and using the peak clipping coefficient to perform peak clipping to the peak-to-average ratio signals of the carrier waves. By the disclosure, the complexity of the generation of the peak clipping coefficient is simplified, the deterioration degree of EVM is reduced, and the distortion degree of signals is also reduced.
