在AWGN信道下实现QPSK系统的仿真 包括求误码率及功率谱密度及星座图(Simulation program to realize QPSK transmission system under AWGN channel)

说明：  这是一个混沌的Anrold变换 他是一次变换加密 是一个混沌加密入门程序(This is a chaotic Anrold transform He is a transformation encryption is a chaotic encryption entry procedures)

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

用脉冲响应不变法和双线性变换法设计数字带通滤波器(Impulse response using the same method and bilinear transformation method the number of band-pass filter design)

MD5 encryption and decryption by srp

BP神经网络用于分类与回归的matlab源码 注释很详细(1、NeuralNetwork_BP_Classification.m- 分类 2、NeuralNetwork_BP_Regression.m- 回归 )

说明：  利用matlab gui制作的图片放大的软件。。(Produced using matlab gui image zoom software. .)

说明：  matlab实例精讲，适用于新手上路，非常全面(matlab examples Jingjiang, suitable for beginners on the road, very comprehensive)
