上传的代码是 matlab宝典的代码 相信对于开发的人员是有帮助的(From the code book is the matlab code and I believe that the development of the staff was helpful)

This code simulates a communication AWGN channel with matlab. You can specify No (noise spectral power) and Eb (bit energy).

一些滤波器设计方法的演示程序，包括窗函数法等，程序之中会有注释，主要是用来学习数字信号处理(Some filter design methods demonstration program, including the window function method, etc., will be among the program notes, is primarily used for learning digital signal processing)

实现粒子群算法的pid整定，适应于simulink模型的仿真，效果不错(Realize the pid tuning of particle swarm optimization algorithm, adapt to the simulation of simulink model, the effect is good)

说明：  旋转不变性子空间（ESPRIT）类算法需要对阵列接收数据协方差矩阵进行特征分解。ESPRIT 类算法是利用接收数据协方差矩阵的信号子空间的旋转不变性，它利用各子阵的信号子空间之间的旋转不变性求出信号的入射角信息。(Rotation invariant subspace (ESPRIT) algorithms need to decompose the covariance matrix of array received data. ESPRIT algorithm is based on the rotation invariance of the signal subspace of the received data covariance matrix. It uses the rotation invariance between the signal subspaces of each subarray to obtain the incident angle information of the signal.)

2008年脑电竞赛的MAT数据。想要的可以直接下载 可以把数据放在MATLAB中直接处理(MAT data of the 2008 EEG competition. If you want, you can download it directly, and you can put data in MATLAB directly.)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据(The introduction was done with the principle of the QPSK modulation and demodulation in digital communications, a script was written by using Matlab program to carry out a simulation of the QPSK communication system ,which contains the concrete realization of transmit and receive process. The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise, spectral analysis of each module is also done, the results obtained with theoretical results in the main, which provides an effective frame of reference for understanding the performance of QPSK systems, and the practical application in the system to make further designed.)

初学matlab的教程，比较全面，比较实用，此部分为第一部分。(Matlab beginner tutorial, more comprehensive, more practical, this section is the first part.)
