Mann Morrison SOurce code

用matlab程序模拟了多层平板波导的导波情况 包括TE模和TM模 该程序可进一步扩展(Matlab procedure used to simulate the multi-layered slab waveguide, including the guided wave TE mode and TM mode of the program can be further expanded)

this program is for signal generation in the matlab

说明：  这是一个LMBP算法的源程序MATLAB(THIS IS A LMBP PROGRAM)

基于matlab的QPSK信号生成，已加噪。(QPSK signal generated)

算术编码实例，matlab编写的简单编码过程(encode symbol)

扩展卡尔曼滤波的程序，十分好用，卡尔曼滤波。扩展卡尔曼滤波 EKF(Extended Kalman filter procedure is very easy to use, the Kalman filter. Extended Kalman Filter)

FIR数字滤波器：里面包含四部分程序，分别对一个给定的信号进行低通滤波，高通滤波，带通滤波，带阻滤波（程序有详细的注释，适合新手学习FIR型数字滤波器）(FIR digital filter: which contains four parts of the program, respectively, for a given signal low-pass filter, high pass filter, band pass filter, band stop filter (detailed comments procedures for novice learning FIR digital filter))

说明：  变化参数，实验LOG边缘检测算法。参数越大，则最后图像边缘检测的轮廓的图像细节也就越少。(Change parameters, experimental LOG edge detection algorithm. Parameter is larger, the final contour edge detection of the less image detail.)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)
