4个不同信道环境下误码率的分析，基于信噪比SNR的，通信方面(four different channel bit error rate environment analysis, based on the SNR, communications)

This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution (TFD) is defined by com-bining FS computed using windows of varying lengths and chirp rates. The IF of individual signal components is then computed by applying a peak detection and component extraction procedure

很好的学习matlab的资料，很精细，适合于初学者，有助于突飞猛进(Good learning matlab, very fine, suitable for beginners, contribute to the rapid)

文件最前面标有svpwm的表示该文件：三相电源先通过二极管整流，在用IGBT以svpwm方式三相逆变，驱动电机运转。 其他的都是simulink中对一些常用模块的功能进行比较简单的练习(File front marked with svpwm representation of the file: the first three-phase power rectifier diode, IGBT svpwm three-phase inverter drive motor running. Simple exercises are simulink some commonly used module functions)

说明：  求信号处理中的峰值信噪比，学通信与仪器的都可用(peak signal noise ratio)

完整的OFDM仿真Matlab程序。从发射机到接收机。(Complete OFDM simulation Matlab. From transmitter to receiver.)

背景差检测运动目标，个别子程序需要自己编写(Background subtraction detection of moving targets, individual subroutines need to write your own)

说明：  lms算法的仿真和yule_walker方程的仿真。这两种算法都是随机信号处理的有效方法。(lms algorithm yule_walker of the simulation and the simulation equations. These two algorithms are effective random signal processing methods.)
