希望多大家有所帮助。尤其是对电子感兴趣的同学(xingwangdajiagangxingqu )

关于OPNET里的一个仿真场景，还是可以参考一下，具体对新手还是比较适用的(OPNET in a simulation on the scene, or can refer to the specific comparison to the novice or the applicable)

matlab 实用程序，非常不错，内容丰富，适合广大初学者(Matlab practical procedures, very good, rich in content, suitable for the majority of beginners)

在用matlab做语音信号处理时经常用到的enframe等函数，这在matlab中是没有的，需要下载专门的工具箱，这是从官网上下载的，可直接解压安装。具体安装方法网上一搜就能搜到。(Frequently used in speech signal processing using matlab enframe function in matlab there is no need to download a special toolbox, which is downloadable from the official website, you can directly extract the installation. Specific installation methods online search can be found to)

在matlab的小波分析中标,设计一个包含若干不连续点的一维信号，利用小波变换的模极大提取它的阶梯型边界点。(Matlab wavelet analysis in the successful design that contains a number of discrete points of one-dimensional signals, using wavelet transform modulus maxima extraction of its ladder-type boundary points.)

一篇基于独立分量分析（ICA）的盲信道MATLAB程序(1 Based on Independent Component Analysis (ICA) for blind channel MATLAB program)

题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？ 1.程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去 　　　　　　掉不满足条件的排列。 (Title: There are numbers 1,2,3,4, how many can be composed of distinct three-digit numbers without repetition? Is how much? 1. Program Analysis: fill in the hundred, ten, a bit of the numbers are 1,2,3,4. Composed of all the permutations and then remove the arrangement does not meet the conditions.)

介绍MATLAB基本操作的的教案，很经典(this is for new learner study MATLAB，it is simple and easy)

基于standford大学cioffi教授的经典算法，计算有线信道的无限冲击响应滤波器系数。(Based on algorithm proposed by Prof. Cioffi, calculate the optimal IIR coefficients for cable channel.)

小波分析，对振动信号的分析，用于提取故障特征。(Wavelet analysis, the analysis of vibration signals for extracting fault feature.)
