指出了单一阈值选取规则小波包降噪方法的局限性，提出了一种改进的小波包能量分段阈值降噪方法，并与其他小波包降噪方法进行对比分析。仿真结果表明，较其他小波降噪方法，改进的小波包能量分段阈值降噪方法去噪效果更佳。

This paper points out the boundedness of wavelet packet de-noising with single threshold, it puts forward an improved wavelet packet energy subsection threshold de-noising, and compares with other wavelet packet de-noising. Comparing with other wavelet packet de-noising, the simulation results show that improved wavelet packet energy subsec-tion threshold de-noising is more effective.
