MATLAB CODE FOR DIGITAL COMMUNICATION

说明：  2个程序，MATLAB设计的一个滤波器，将含3个频率分量的信号通过该滤波器，滤除2个高频分量，得到只含低频的信号。 单边带信号调制，用MATLAB实现，是学习信号调制的一个好例子。(Two procedures, MATLAB design a filter, will contain three frequency components of the signal through the filter, filter out high frequency components of two, has been only with low-frequency signal. SSB signal modulation, using MATLAB to achieve, is to study signal modulation of a good example.)

采用harry算法实现对凹点的搜索，基于matlab平台，通过更改参数可以实现凹点搜索的精度(Harry algorithm using concave point of the search, based on matlab platform, can be achieved by changing the parameters of precision concave point search)

用matlab编写的各种信号，比如信号相乘、阶跃信号、脉冲信号、指数信号等(Matlab prepared by the various signals)

matlab和串口通信，利用这个模板，可以做到将实时串口数据交给matlab计算并且实时将计算结果返回。(matlab and serial communication, use this template, you can do real-time serial data to matlab computing and real-time calculation results returned.)

MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)

this program gives the idea about how image is represented in different plane in an 8bit mode.
