OFDM系统中限幅降低峰值与平均功率比的matlab实现，可以直接运行，会有点慢(OFDM system, limiting the peak to average power ratio reduction of the matlab implementation, can run a bit slow)

结合emd和bp神经网络的算法, 对轴承故障数据进行诊断,数据可以自己添加(EMD and BP algorism are combined to classify different kinds of faults of bearings. Source data need to be added by yourself)

受光照影响的人脸预处理算法，使用小波变换和同态滤波(Affected by light Face preprocessing algorithm, using wavelet transform and homomorphic filtering)

MIMO系统的各种空时分组码仿真 包括2*2 alamouti编码，1/2速率的空时分组码(MIMO system simulation of space-time block codes, including 2* 2 alamouti coding, 1/2 the rate of space-time block codes)

说明：  此程序为模糊PID控制程序，自适应模糊PID控制器以误差e和误差变化率e 作为输入，可以满足不同时刻的e和e 对PID参数自整定的要求。利用模糊控制规则在线对PID参数进行修改，便构成了自适应模糊PID控制器。 (procedure for fuzzy PID control procedures, adaptive fuzzy PID controller error e and e error rate of change as input to meet the different moments of e and e PID tuning parameters from the request. Fuzzy-control rules on PID parameters changed, they constitute the adaptive fuzzy PID controller.)

说明：  一个用matlab软件做的抽取滤波器的程序，在软件中打开文件仿真后得到6个波形(Software used to do a decimation filter matlab program, open the file in the software simulation waveforms obtained 6)

完整的永磁直驱风电系统模型，包括风轮机，发电机，双PWM变流器，控制系统等(Complete permanent magnet direct drive wind power system model, including wind turbines, generators, dual PWM converters, control systems, etc.)

说明：  IEEE33节点的并网风力发电可直接运行(The grid connected wind power generation of ieee33 node can operate directly)

神经网络中用矩阵分块的方法处理数据量过大的情况，效果很好(Neural network is used in the method of matrix blocking deal with the situation of the large amount of data, the effect is very good )

Fast video loading code do background subtraction subtracting all frames from first frame and show the result video so fast
