基于Wiener滤波的语音消噪Matlab源程序 调用方式： output=WienerScalart96(signal,fs,IS) signal－－输入含噪语音 fs－－－－语音信号采样率 IS－－－－起始静音端，用来估计噪声方差（秒做单位，默认是0.25秒） (Wiener filter-based de-noising of the voice call Matlab source code the way: output = WienerScalart96 (signal, fs, IS) signal- voice input with noise fs---- voice signal sampling rate IS---- Start mute end used to estimate the noise variance (units of seconds to do, the default is 0.25 seconds))

Finite-difference time-domain (FDTD) is a popular computational electrodynamics modeling technique. It is considered easy to understand and easy to implement in software.

基于一阶AR模型u(n)=0.99u(n-1)+v(n),白噪声方差0.93627.步长0.05.分别使用M=2和M=3抽头的滤波器，用LMS算法实现u(n)的线性预测估计。并附仿真图已被参考。(Based on a first-order AR model u (n) = 0.99u (n-1) the+v (n), the white noise variance 0.93627 step 0.05. Respectively with M = 2 and M = 3-tap filter, with the LMS algorithm u (n) of the linear prediction estimates. Along with simulation diagram reference.)

选择五个不同频段的信号对其进行频谱分析，根据信号的频谱特征设计五个不同的数字滤波器，将五路信号合成一路信号，分析合成信号的时域和频域特点，然后将合成信号分别通过设计好的五个数字滤波器，分离出原来的五路信号，分析得到的五路信号的时域波形和频谱，与原始信号进行比较，说明频分复用的特点。(To select one of five different band signal spectrum analysis and design of five different digital filter based on the spectral characteristics of the signal, the the Rd signal synthesizing all the way to the signal analysis in time domain and frequency domain characteristics of the synthesized signal, and then the synthesis signal by five digital filter designed, separated original signal Rd, the time-domain waveform and spectrum analysis the Rd signal is obtained, to be compared with the original signal, the frequency division multiplexed with the characteristics.)
