PulseCodeModulation

说明：  是ｍａｔｌａｂ相关的基础学习，在我们学校小学期的时候用到了(Matlab based learning in our school primary school period when used)

这是应用emd分解之后，并与原信号进行相关分析的matlab程序(this is a program which contains emd and correlation analysis with the original signal)

CFAR阈值 -逆高斯分布的CFAR检测阈值，计算公式带积分，考虑能否用高贵软件小目标CFAR公式阈值代替？？利用查表法！(CFAR threshold- inverse Gaussian distribution of CFAR detection threshold, the formula with integral, consider whether the use of noble software small target CFAR formula threshold instead? ?? Use look-up table method!)

FSK信号的频带仿真，采用的是最基本的带通加低通的解调形式(Simulation of FSK band signal)

（1）通过Simulink创建仿真模型；（2）配置相关RTW（Real-Time Workshop）参数；（3）通过RTW（Real-Time Workshop）自动生成C代码文件，并理解主要文件、接口函数和变量的意义；（4）在Visual C++中将生成的C代码作适当修改，编译运行并分析结果。((1) created by Simulink simulation model (2) configuration related to RTW (Real-Time Workshop) parameters (3) RTW (Real-Time Workshop) automatically generate C code files, and understand the main document, interface functions and variables significance (4) Visual C++ generated C code will be modified as appropriate, compile, run and analyze the results.)

计算滤波器的冲击响应，阶跃响应，幅频响应和相频响应(calculating the impulse response filter, step response, frequency response and phase frequency response)

本程序为一个extended kalman filter的matlab代码，可以帮助那个想学习extended kalman filter的(This program is an extended on kalman filter matlab code that can help that want to learn extended on kalman filter)

序列进行离散傅里叶级数变换，画出相位图，频谱图。改变序列长度，然后重复上述过程(Sequence of discrete Fourier series transform, draw the phase diagram, spectrogram. Change the length of the sequence, and then repeat the process)

DOA估计与阵元数关系的MUSIC程序，可完成MATLAB的波形仿真。(DOA estimation the the MUSIC program relationship with the number of array elements, to be completed by MATLAB waveform simulation.)

自适应粒子群算法的应用程序，用matlab编写，适合初学者使用(adaptive PSO algorithm)
