这个是对PL-logdist和PL-lognormal的一个仿真。程序简单易懂，但是意义不小。有专门的画图子程序。(This is a PL-logdist and PL-lognormal a simulation. Procedures are simple, but the meaning is not small. Have a special drawing routines.)

一种eemd程序，为学习emd的同学做参考，希望大家多交流学习~(an eemd program，as a reference~)

以最小二乘法进行曲线拟合 得到概率密度函数的参数(With the least squares curve fitting to get the parameters of the probability density function)

A Repetition Code with rate=1/2,A Generator Mrtrix and Uncoded System .these codes shows the performance of their in BSC channel.

dijkstra code at matlab

this is the example for matlab GUI

GOld码为ca码的一种，在扩频系统中，得到广泛应用，此代码为一段ca码产生程序(Gold code generator program)

一、实验要求 信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为和，初始相位，取，取不同数值：0.3，0.25。为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Power spectrum estimation)

应用LMS算法去除噪声，纯净信号为各种数字调制信号，本程序中选的是数字调幅信号8ASK，噪声是高斯白噪声，信噪比可以任意指定。(Application of LMS algorithm to remove noise, clean signal for a variety of digital modulation signal, this procedure is successful digital AM signal 8ASK, noise is white Gaussian noise, signal to noise ratio can be specified.)

说明：  绘制星座图的程序，主要要是QAM的仿真，希望大家看看。基于小波的星座图仿真(Constellation diagram drawing program, the main if the QAM simulation, let us look. Wavelet-based Constellation Simulation)
