Program to plot the BER of OFDM in Frequency selective channel

说明：  MATLAB短时傅里叶变换和morlet小波变换(short-time Fourier transform and morlet wavelet transform based on matlab)

matlab code for genetic

解二次函数的LBFGS算法,包括几个子程序，并且用了wolfe 线性搜索法(LBFGS algorithm for solving quadratic function)

多变量无约束问题的优化最优化方法之梯度下降法(Optimization of the gradient descent method)

说明：  在用matlab的时频分析中，不是所有信号的wvd都是可以，一些特殊的信号要用特殊的窗口来得到较好的效果(using Matlab in the time-frequency analysis, not all signals can be wvd, some special signal use special window to get good results)

说明：  FSK在Rayleigh 衰落下的matlab误码率仿真，包括理论计算和仿真结果(FSK in Rayleigh Fading matlab error rate simulation, including theoretical calculations and simulation results)

The proposed filter is able to suppress high-density of salt-and-pepper noise, at the same time preserving fine image details, edges and textures well.

关于图像恢复的程序。输入恢复类型、待恢复图像的相关文件（程序中具体列出）和图像数量即可恢复出原图像和恢复情况评估。(With regard to the procedures for image restoration. Enter the recovery type, you can restore the image file to be restored (specifically listed in the program) and the number of images of the original image and restore the situation to assess.)

关于多径信道的matlab的子函数实现，Jakes模型等都包含(On the multi-path channel to achieve the matlab s Functions, Jakes model contains all)
