Title: A Peak Signal Denoising Method for Mobile Communication Network
Abstract: A peak signal denoising method for mobile communication network is presented based on improved empirical mode decomposition( EMD) algorithm. The method decomposes the peak signal into different frequency bands from high to low by using empirical mode decomposition principle,and moves the peak signal in each band reversely according to the wavelet threshold. The peak signals in different frequency bands are estimated based on the wavelet threshold,and the average value is calculated. Then the refactored peak signal is obtained,and the peak signal denoising is accurately implemented. Simulation results show that the proposed algorithm can achieve stable and robust denoising effect.
