摘要
Abstract
Aiming at avoiding the existing problem of end effects and mode mixing in empirical mode decomposition, a new method is proposed. By using the method of mirror image extending to extend the signal data at both ends, then pro-cessing by cosine window function, the influence of end effects on decomposition results is solved. Using the method of high-frequency harmonics, it combines with the masking signal to inhibit the mode mixing of empirical mode decomposi-tion. Simulation results indicate that the new method is effective and feasible.关键词
