说明：  直扩系统，适合学生毕业设计，结构简单，使用方便(DS system, suitable for graduate students to design, simple structure, easy to use)

PSO (particle swarm optimization)

对测试图像进行基于PCA的特征提取,然后在特征空间进行标示(PCA-based feature extraction, and then the test image in the feature space marked)

本书籍包括所有无线通信系统中的数学模型，内容丰富。(environmenet of wireless communication)

具有反馈的BP神经网络Matlab实现，可用于预测。(With feedback of BP neural networks realize Matlab can be used for prediction.)

说明：  用Matlab编的BPSK程序，简单准确(Using Matlab program for the BPSK, simple and accurate)

污染模拟软件，matlab实现，非常好的程序，数模建模经常用到(Pollution simulation software, matlab realize, very good program, frequently used digital-analog modeling)

这个我用matlab写的一个简单孤立词语音识别的程序，其中同过预处理，ＭＦＣＣ提取，和ＤＴＷ算法的比较，如果大家愿意，还可以用这个和ＬＡＢＶＩＥＷ联合编程(Matlab write this I used a simple isolated word speech recognition procedures, which had the same pretreatment, MFCC extraction, and the DTW algorithm, if everyone is willing, but also can use this joint programming and LABVIEW)

双二进制信号是一种信号体制利用码间干扰作为一种控制方式而不是消除码间干扰(Duobinary signaling is a three level signaling scheme that uses intersymbol interference in a controlled way instead of trying to eliminate it. )

用matlab 实现ofdm,输入的是长度为256的随机序列，其中用到了opsk调制，ifft和fft变换(Using matlab realize ofdm, enter the length of the random sequence 256, which uses a opsk modulation, ifft and fft transform)
