OFDM_OPTIMAL_rx

This code sorts a integer vector using QuickSort with p-threads.

这组代码模拟了整个信号的编码，调制，解调，译码在无线通信，其中包括A-law扩展，PCM和的2PSK调制解调的技术过程。(This collection of codes simulates the whole signal encoding, modulation, demodulation, decoding process in wireless communication, which involves the techniques of A law companding, PCM, and 2PSK modulation and demodulation.)

GA(PSO)为GA和PSO单独优化算法，里面分了两个文件 一个PSO粒子群算法 一个GA遗传算法(GA (PSO) for GA and PSO optimization algorithm alone, which divided the two documents a PSO PSO algorithm a genetic algorithm GA)

无线通信抗衰落，合并器输出信噪比的概率密度函数比较。选择性合并，最大比率合并，等增益合并的概率比较(Slow Fading Plot Outage Probabiloty vs SNR for maximum ratio combining, coherent combining and antenna selection.)

说明：  matlab实现的对样本视频的混合高斯模型的检测代码(Sample video detection code Gaussian mixture model)

说明：  welch 法加汉宁窗对高斯白噪声信号进行功率谱分析(welch Fajiahanning window on the Gaussian white noise signal power spectrum analysis)

说明：  KPCA实现数据降维，数据部分可以自己改，用的是TE故障中的一组数据(KPCA realizes data dimension reduction, and the data part can be changed by itself. It USES a set of data in TE fault)
