在matlab环境下对chen系统的仿真，希望对于学习者有用(Chen system simulation in Matlab environment useful for learners)

现代通信系统(MATLAB版)(第二版)刘树棠译 本书系Brooks/Cole出版公司（Thomson Learning出版集团的下属子公司）2000年推出的BookWare系列丛书（BookWare Companion SeriseTM）之一种。该书提供了利用MATLAB的普及型学生版本在计算机上解决“现代通信系统”这门课程中涉及的几乎所有方面的问题的分析思路、方法、MATLAB脚本文件和处理结果的范例以及供学生自主学习研讨的习题。全书内容分为9章，分别是：信号与线性系统；随机过程；模拟调制；模拟/数字转换；基带数字传输；带限信道的数字传输；载波调制的数字传输；信道容量和编码；扩频通信系统。 (This book Brooks/Cole Publishing (Thomson Learning Publishing Group, a subsidiary) in 2000 launched BookWare Series (BookWare Companion SeriseTM) of a kind. The book provides the advantage of the popularity-based student version of MATLAB on the computer to solve the " modern communications systems," This course covered almost all aspects of the analysis of ideas, methods, MATLAB script files and processing the results of examples, as well as independent study for students seminar to answer. The book consists of nine chapters, namely: Signal and Linear System stochastic process analog modulation analog/digital conversion base-band digital transmission band-limited channel digital transmission carrier modulation digital transmission channel capacity and coding spread-spectrum communication systems.)

深入浅出matlab 7.x混合编程，一本非常详细的介绍matlab7.x与VC之间通过各种方式混合编程的实现方法(Layman matlab 7.x mixed programming, a very detailed introduction matlab7.x and VC mixed programming through a variety of ways to achieve method)

ifft和fft实现线性卷积,并与matlab中默认内置的conv()函数的结果对照，验证其正确性。(using ifft and fft to accomplish linear conviction. Comparing this method with matlab default function conv().)

matlab基本操作的实验，含具体操作及报告(matlab basic operation of the experiment, and reports with the specific operation)

这是我自己在学习中自己收集的一些基于MATLAB的MIMO源代码，有些是自己写的 有些是参考别人的 还有一些mimo的资料，觉得对于通信领域的学习者会很受用(This is some source code about mimo system and some reference about that)

说明：  可以将图的颜色在0位置表现为白色，使用方法为multimap函数，注意将范围设为对称，这样就可以将0设为白色(Can map the location of the performance of the color 0 is white, the use of methods for Multimap function, set the scope of attention to symmetry, this can be 0 is set to white)

基于pso算法优化的PID神经网络的系统控制算法(Pso optimization algorithm based on neural network PID control system algorithm)

模糊自适应推理系统的程序，用过效果挺好。(Adaptive fuzzy inference system procedures, used very good effect.)

傅立叶变化的Matlab实现，对于学习FFT非常有帮助。FFT文件夹内有多个程序。(Matlab Fourier realize change, for learning FFT very helpful. FFT folder has a number of procedures.)
