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))

利用matlab simulink软件中的communication blockets（通信模块）对psk数字传输系统进行动态、可视化仿真，清晰地表现psk传输系统组成及各项性能指标(Using matlab simulink software communication blockets (communication modules) of psk digital transmission system for dynamic, visual simulation, the performance of psk clear the transmission system components and performance indicators)

一个关于多相位调制的matlab仿真程序，非常好用，是做毕业设计时完成的。(A multi-phase modulation on the matlab simulation program is very easy to use, is doing graduate design completed.)

通过MATLAB来计算阵列天线，包括线性阵列，平面阵列，还有圆形阵列(Calculated by MATLAB array, including linear arrays, planar array, as well as circular arrays )

在MATLAB软件环境下运行 产生升余弦滚降函数波形及眼图图像(Run in the MATLAB software environment created Cosine function waveform and eye diagram image)

有源低通巴特沃斯滤波器设计根据给定的参数值设计有源滤波器(Active low-pass Butterworth filter design parameters according to the given active filter design)

实验结果表明该算法对非冲击噪声效果良好。 lx_main为主程序，NS_lxwz为噪声估计模块，lxG_wz为增益估计模块，noise_sound为测试用含噪语音。 算法原理参见本人的文章《一种引入延迟的语音增强算法》。(Experimental results show that the algorithm for non-impulsive noise effect is good. lx_main the main program, NS_lxwz for the noise estimation module, lxG_wz for the gain estimation module, noise_sound to test the noisy speech. Algorithm theory see my article " delay the introduction of a speech enhancement algorithm." )

说明：  使用交互式多模型技术，滤波器选择无迹卡尔曼滤波器。(We use ukf to achieve imm successfully)
