信号处理中的经典MUSIC算法，包括直线阵，圆阵，平面阵L阵(MUSIC classical signal processing algorithms, including linear array, circular array, planar array array L)

激光光束在介质中传播的分析及仿真，可仿真光束传输特性，程序运行结果较为直观，(Laser beam propagation in the medium analysis and simulation, the beam transmission characteristics can be simulated, the program operating results are more intuitive,)

说明：  简单实用的SLM法降低OFDM峰均比。。。(matlab SLM method to reduce PAPR ofdm。。。)

读取以.dat的数据文件；读取以MIT-BIH数据库的212格式文件(Read the MIT-BIH database 212 format data)

这是基于matlab编写的一套用于指纹识别的源码，可以即得即用，很是详细。(This is based on the preparation of a set of matlab source code for fingerprint recognition, which you can get that is used, it is detailed.)

同态滤波 MATLAB code for beginners that performs Homomorphic filtering, Using Butterworth High Pass Filter for performing filtering.(Copy the files in your work space Type "ho_filter" to see the results)

直方图均衡化 直方图的均衡化可以使图像的像素灰度值动态范围变大，增强图像的对比度看起来更清晰。上图经过直方图均衡化方法处理后不再特别暗淡，其直方图反映出来的灰度的概率分布也相对比较均匀(Histogram equalization)

本程序验证手写fft频谱分析的正确性，并用于信号频域积分和频率检测。包含文档详细解释。(This procedure verified the correctness of handwritten fft spectrum analysis, and for the signal frequency-domain points and frequency of testing. Contains the document explained in detail.)

产生M序列，可以作为系统的输入，经过系统辨识后得到输出，进而得到系统的传递函数(M sequences generated can be used as the input, output obtained through system identification, and further to the transfer function)

代码给出几种不同的信道模型对应的matlab仿真，代码精确无错，适合初学者自学(we have considered the general large-scale fading characteristics of wireless channels)
