人脸识别的matlab程序，不过是一个主程序界面，要是用的话还得调用很多的子程序(Face recognition matlab program, but is a main program interface, if used, then have to call a lot of subroutines)

用matlab实现的曼彻斯特 DLFQKC编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的WMMygYW 的通信原理课件上的形状一模一样。 .(With Manchester DLFQKC encoding matlab realize. 50 duty cycle (adjustable) . Draw time-domain waveform and frequency domain power spectral density. Results with BUPTWMMygYW Exactly the same shape Wenbin communication on the principles of courseware.)

对于一个含有明显噪声的心电信号进行卡尔曼滤波处理，最大程度地 “还原”信号，达到去除噪声的目的。卡尔曼滤波（看成维纳滤波的一种实现方法）的特点如下： a) 是根据上一状态的估计值X(n-1)和当前状态的观测值Z(n)推出当前状态的估计值X(n)的滤波方法,不需要用过去的全部观测值。 b) 它是用状态方程和递推方法进行估计的，因而卡尔曼滤波对信号的平稳性和时不变性不做要求。 c) 使用全部观测值保证平稳性。(Kalman in matlab,if you need it,please download it.)

说明：  TDOA说明，五个麦克风阵列找到声源位置和方向(TDOA shows that five microphone arrays find the location and direction of the sound source)

说明：  这是一个短时傅里叶变换的程序，特别详细，超级好用(This is a short-time Fourier transform procedure, particularly detailed, super-easy)

A计权滤波器,用于声音信号的A计权滤波，需要声压信号和采样频率，即可得到滤波后的时程信号(A weighting filter, A weighting filter for voice signal, need sound pressure signal and the sampling frequency, you can get the schedule of the signal after filtering)
