说明：  放大转发（DF）matlab环境下的通信系统仿真(Amplify and forward (DF) Matlab environment communication system simulation)

说明：  采用matlab编写，基于OPTA细化算法，适合入门级新手用，希望对大家有用(Using matlab to prepare, based on OPTA thinning algorithm, suitable for entry-level novice, and I hope useful for all of us)

这是利用MATLAB来模拟色子，一个非常实用在程序(This is the use of MATLAB to simulate the dice, one very useful in the 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)

These programs are used to calcualted a Duel phase lag model with different methods.

改程序包里包含中值、均值滤波、自适应中值滤波和一种改进的椒盐噪声滤波程序，前三种是给第四种作对比的，第四种方法对椒盐滤除效果很好。(Change the program package contains the value, mean filtering, adaptive median filter and an improved impulse noise filtering program is the first three compare to the fourth, the fourth method works well for removing salt and pepper.)

内罗梅综合指数分析法Nemerow integrated index(Nemerow integrated index)

一天征服傅里叶变换，对傅里叶变换做了浅显易懂的分析，对学习数字信号处理有帮助。(One day conquer the Fourier transform, made accessible for the Fourier transform analysis, is helpful to study digital signal processing.)

这是一个基于粒子群算法来寻找图片上的园的圆心，通过自己设置参数，可以在较短的时间内较为精确的找到一个图所有圆的圆心(It is used to find the location of circles in a complicant map. For this fuction, you can set some paraement yourself and it will return the result in a very short time. )
