摘要 针对硬阈值函数在阈值点不连续,软阈值函数中估计的小波系数与信号的小波系数之间存在着恒定偏差的缺陷,构造了一种新的阈值函数,仿真结果显示,该方法具有较好的去噪结果。 The hard threshold function is discontinuous on the threshold value, and there are some disadvantages in soft threshold function. So a new threshold function is produced to overcome the shortcomings. And the Simulation results indicate that the new method has improved the effect of denoising.
