傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。-ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier tran

该文档为一实际的自适应维纳滤波器设计实验，可用于语音信号消噪与图像滤波，为传统维纳滤波器的改进。-This document is a practical adaptive Wiener filter design of experiments, the speech signal can be used to eliminate noise and image filtering, to improve the traditional Wiener filter.

语音增强，消噪,非常简单实用的matlab源程序，属于语音信号处理的范畴。(speech enhancement,noise reduction)
