用MATLAB画一个弯曲的圆柱 思想：把圆柱按轴线分若干段，在每个断面画圆，圆的法线就轴线的切向方向。柱面画若干平行于轴线的线条，其中用到平行单位矢量点积等于1，不平行的结果是[-1，1）。 (MATLAB painting with a cylindrical curved thinking: the cylinder axis by a number of sub-paragraph in each section drawcircle, round on the normal axis of the tangential direction. Painted a number of cylindrical axis parallel to the lines, which use a parallel unit vector point plot equal to 1, the result is not parallel to [-1,1).)

该程序用来实现发端的调制，其中包括BPSK、QPSK以及16QAM等调制方式(The program used to implement the originator of the modulation, including BPSK, QPSK and 16QAM modulation, etc.)

使用平均方差的方法实现加性和乘性噪声的去除(The method used to achieve the average variance of additive and multiplicative noise removal)

说明：  csharp和matlab混合编程的视频教程，很不错(csharp and mixed programming matlab video tutorial, very good)

王丰华等提出的相位差分法的实现，主要用于信号处理中提取信号的瞬时频率。注意该方法只适用于单分量信号。另外一个是利用自相关法求瞬时频率(Wang Fenghua such as the phase difference method to achieve, mainly used for signal processing to extract the instantaneous frequency of the signal. Note that this method is only applicable to single-component signal)

Montel Carlo图形的重要程序：它可以将MATLAB生成的数据转存到excel中(Montel Carlo)

白噪声过程的功率谱 自相关函数和功率谱(The power spectrum of the white noise process autocorrelation function and power spectral)

在有限区域内分布的稀疏不均的、具有一定分布结构的海量数据集的高效、高精度聚 类问题是一个尚未完全圆满解决的难题。针对Affinity Propagation 聚类算法(AP)的不足之处， 提出了两个改进型的聚类算法(In a limited area of uneven distribution of sparse, has certain distribution structure of the mass datasets of high efficiency, high precision together Problem is a perfectly solved problem has not yet completely. For Affinity Propagation clustering algorithm (AP) of the deficiencies, Put forward the two improved version of the clustering algorithm)

经典的二阶矩四阶矩信噪比估计，有不经过上采样、成型滤波和经过上采样、成型滤波的两种版本。加噪方式也分别用了matlab自带函数和自写两种版本。望大家参考。(Second Moment classic SNR estimation fourth moment, there is not through the sampling, the shaping filter and sampled, two versions of shaping filter. Plus noise mode were also comes with a matlab function and self-written versions. Hope you reference.)
