用于进行频率调制基于MATLAB 环境下的程序(frequency FSK modulation)

本程序可绘制无码间串扰的眼图，可设置显示不同的升余弦滚降系数以及眼图个数！希望对大家有用！(This program can be drawn Uncensored crosstalk eye-diagram, you can set different raised cosine roll-off factor and the number of eye diagram! I hope useful for all of us!)

MATLAB经典周期图法功率谱估计对信号进行功率谱估计。(MATLAB classical periodogram power spectrum estimate of the signal power spectrum estimation.)

关键的3G技术cofdm的相关程序代码，运行效果不错欢迎大家积极下载(key 3G technology cofdm the relevant code, the operating results good to welcome you actively download)

这是对广义高斯分布中两个参数alpha,beta的估计方法，对自然图像的大量统计特征就符合这一分布。(function [f, g] = dggbeta(beta, absx) DGGBETA Derivative of generalized Gaussian pdf with respective to beta [F, G] = DGGBETA(BETA, ABSX) Return partial derivative and second order partial derivative This is an utility function for GGMLE ABSX is the distance of the data from the mean Function is undefined for negative beta if beta <= 0 f = NaN g = NaN )
