simulink做的BPSK的调制与解调，信号源是随机信号与PN码扩频调制，最后结果与随机信号比较一致(simulink do BPSK modulation and demodulation, the signal source is a random signal with the PN code spread-spectrum modulation, the final result more consistent with the random signal)

说明：  matlab图像处理常用命令收集，很有用的，可以省很多时间(matlab image processing common command collection, very useful, can save a lot of time)

对SC-FDE采用不同UW（特殊字）情况下进行误码性能比较，UW类型分别为chu序列和Frank-Zadoff(For SC-FDE using different UW (special characters) for the case of error performance comparison, UW type sequences, respectively, and Frank-Zadoff chu)

利用matlab离线处理数据实现经验模式分解（EMD）算法(Offline data processing using matlab to achieve empirical mode decomposition (EMD) algorithm)

说明：  这个是在二维下，对随机离散的点，生成二维的数据场(This is a two-dimensional, the random discrete points, generate two-dimensional data field)

This Matlab source code is for paper LEACHC for wireless sensor networks.

几种重要的滤波器，中值滤波，fft理想低通滤波，fft高斯低通滤波(median+fft lowpass+fft guass-lowpass)

说明：  求解分数阶微分方程的Runge_Kutta方法Fractional Differential Equations of Runge_Kutta method(Fractional Differential Equations of Runge_Kutta method)

matlab 使用的心得与体会 在使用过程中肯能会遇到的问题(matlab use of the experience and experience in the process of using the point to be encountered)
