自己编的一个用随机行走法实现电路计算的例子，电路图及参数均在Partial random walk for large linear network analysis里(Own a random walk method used to achieve circuit examples, circuit diagrams and parameters in the Partial random walk for large linear network analysis in)

层次聚类算法实现(Using MATLAB to achieve an improved version of Chameleon (chameleon) algorithm)

It is BER vs SNR codes for BPSK and 4QAM

多径效应的时域表示实际上就是不同路径来的信号存在随机的时延差。对于抗其它扩频信号干扰性能，及抗多址干扰性能。我们这里考虑简单的情况，只考虑一个用户干扰的情况，说明其具有抗多址干扰性能就行。(Multipath effect is actually a time domain representation of the signal path to the existence of different random time delay difference. Other spread spectrum signal for the anti-interference performance, and anti-MAI performance. Here we consider the simplest case, considering only one user interference, indicating its performance with anti-multiple access interference on the line.)

说明：  MIT Matlab教程：INTRODUCTION TO MATLAB — Fall 1999 Thomas F. Weiss Last modification September 9, 1999 1(MATLAB is a programming language and data visualization software package which is especially effective in signal processing and systems analysis. This document is a brief introduction to MATLAB that focuses on those features that are of particular importance in 6.003.1 It is assumed that the reader is familiar with Project Athena, has an Athena account, and has little or no experience with MATLAB. Other MATLAB help is available through Athena consulting which offers a number of more tutorial handouts and short courses (ext. 3-4435), on-line consulting (type olc at the Athena prompt), and Athena on-line help (type help at the Athena prompt). There are a number of books available that describe MATLAB. For example, Engineering Problem Solving with Matlab, by D. M. Etter, published by Prentice-Hall (1997) and Mastering MATLAB, by Hanselman and Littlefield, published by Prentice-Hall (1996). The paperback MATLAB Primer by K. Sigmon, published by CRC Press (1994) is a handy summar)

文章对非线性系统进行了故障诊断，并做了容错控制，并用仿真实例很好滴证明了！(This paper discusses the fault diagnosis of nonlinear systems and fault-tolerant control, good drop by simulation examples prove!)
