Binary Phase Shift Keying Simulation for BER v/s SNR of Additive White Gaussian Noise Channel

研究生时的现代信号处理的作业，小波包分析提取振动信号中的特征频率，已调制信号计算其普相关密度。( Modern signal processing jobs when the graduate, Wavelet packet analysis to extract vibration signal characteristic frequency, Modulated signals to calculate its density Pu-related.)

matlab程序设计教程，供初学者最快熟悉MATLAB基本操作。(matlab programming tutorial for beginners the basic operation of the fastest growing familiar with MATLAB.)

基于小波变换的数字音频水印算法 水印嵌入源程序 (With the rapid growth of computers, network and multimedia technologies, powerful and low cost computers allow people to easily create and copy digital products of multimedia. The Internet has made it easy to distribute the information at very low cost. However, these technologies also can be illegally copied, modified and redistributed multimedia data without regarding for intellectual property rights ownership. )

basic code when you learn objective-c.

这是一个标准的Elman的程序外加一个利pso算法优化Elman神经网络权值的程序，可以运行出图，简单易懂！(This is a standard procedure plus a profit Elman pso algorithm to optimize Elman neural network weights program, you can run out of maps, easy to understand!)

一个用simulink做的模糊PID自适应系统，FIS等都比较简单，适合初学者。通过与PID的比较曲线可以看出此系统更加优越。(A simulink do with self-adaptive fuzzy PID system, FIS are relatively simple, suitable for beginners. Comparison with the PID system curve can be seen even more superior.)

性指标的价值函数达到最小。FCM与HCM的主要区别在于FCM用模糊划分，使得每个给定数据点用值在0，1间的隶属度来确定其属于各个组的程度。与(indicators of the value of minimizing function. HCM FCM with the main difference is fuzzy FCM, broken down to make each set of data points with the value 0, one of the membership to determine its belong to the group level. And)
