模拟OFDM系统，根据不同的信噪比，测试误码率(Simulated OFDM system, according to different signal to noise ratio, bit error rate test)

基于MATLAB编程的粒子群算法，测试函数为shaffer(MATLAB programming based particle swarm algorithm, test function shaffer)

比较多用户信号检测各个算法的误码率，如最小均方、最大似然等(MUD,ML,MMSE)

不错的GM_EM代码。用于聚类分析等方面。( GM_EM- fit a Gaussian mixture model to N points located in n-dimensional space. Note: This function requires the Statistical Toolbox and, if you wish to plot (for k = 2), the function error_ellipse Elementary usage: GM_EM(X,k)- fit a GMM to X, where X is N x n and k is the number of clusters. Algorithm follows steps outlined in Bishop (2009) Pattern Recognition and Machine Learning , Chapter 9. Additional inputs: bn_noise- allow for uniform background noise term ( T or F , default T ). If T , relevant classification uses the (k+1)th cluster reps- number of repetitions with different initial conditions (default = 10). Note: only the best fit (in a likelihood sense) is returned. max_iters- maximum iteration number for EM algorithm (default = 100) tol- tolerance value (default = 0.01) Outputs idx- classification/labelling of data in X mu- GM centres)

matlab环境下的前推后代法潮流计算程序，是7个节点的配电网。(before pushing sweep method flow calculation program matlab environment, the distribution network is seven nodes.)

说明：  比例准谐振控制器 求差分方程系数函数, 比例谐振（PR）控制器的学习过程记录(Proportion, Resonant, PR)
