基于Matlab的小波阈值折衷去噪算法研究

基于硬阈函数和软阈函数的小波去噪算法处理的信号分别存在着偏差和方差过大的缺点，为有效解决这一问题，提出基于硬软阈值的折衷小波去噪算法。并采用四种常用的信号用matlab对去噪效果进行了仿真。仿真结果进一步表明了基于硬软阈值折衷去噪算法的优越性和有效性。

Research on Wavelet Threshold Compromise Denoising Method based on Matlab

Shortcomings of large deviations and variances always exist in the process of information denoising based on the hard or soft threshold method.In response to that,a compromise method based on the hard and soft threshold is proposed and four ordinary signals are also brought into the process of information denoising experiments.The result for that further demonstrates the superiority and effectiveness of this method.
