说明：  我们提出了一种改进的小波域维纳滤波器，在小波域采用基于贝叶斯估计的小波阈值去噪技术估计期望信号提高估计的精度，并以此设计经验维纳滤波器
(We propose an improved wavelet domain Wiener filter in wavelet domain Bayesian estimation based on wavelet threshold denoising techniques to estimate the desired signal to improve the accuracy of estimates, and this Wiener filter design experience)
