说明：  该算例是利用蒙特卡罗算法来实现对pi的估值，压缩包中有运行结果图及程序说明，程序是用matlab代码实现(The study is the use of Monte Carlo algorithm to achieve the valuation of pi, compressed package in the results map and description of the procedures, the program code with matlab)

1. 对LBG算法的理解和使用； 2.Matlab矩阵数据的处理。(Understood that the use of vector quantization for image quantized principle: a number of samples of the sequence are jointly quantified, instead of a similar set of values ​ ​ with a value, to reduce the quantization error master Vector quantizer codebook design, the experimental use LBG algorithm codebook design 3. LBG algorithm to understand and use 4.Matlab matrix data processing.)

说明：  采用频率调制 为1000Ｈｚ的载波，在解调前把加性白高斯噪声加入到调制信号。当噪声功率和调制信号功率比为０.００１，０.０１，０.０５，０.１和０.３是进行解调并绘出调制信号(The use of frequency modulation for the 1000Hz carrier, in the demodulation before AWGN added to the modulation signal. When the noise power and modulation signal power ratio of 0.3 is 0.001,0.01,0.05,0.1 and demodulation and modulation signals mapped)

espritsus算法的matlab实现，可以得到好的实验效果。(espritsus algorithm matlab implementation, can be a good experiment results.)

OFDM的LDPC编码调制程序，非常有用哦！经过学习，肯定可以掌握的！(The LDPC coded OFDM modulation process)

C=CURVEFIT( 拟合模型 ,参数C初值,X数据,Y数据) 求参数C使得 sum {(FUN(C,X数据)-Y数据).^2}最小化(C = CURVEFIT ( fitting model and parameter C, initial X, Y data) for data parameters that sum {there (C) (C, X-ray data- Y j ^ 2) minimizing})

此为一篇介绍mcmc方法的外文文献 非常适合刚刚接触mcmc方法的初学者(This paper introduces the readers of the Proceedings to an important class of computer based simulation techniques known as Markov chain Monte Carlo (MCMC) methods. General properties characterizing these methods will be discussed, but the main emphasis will be placed on one MCMC method known as the Gibbs sampler. The Gibbs sampler permits one to simulate realizations from complicated stochastic models in high dimensions by making use of the model’s associated full conditional distributions, which will generally have a much simpler and more manageable form. In its most extreme version, the Gibbs sampler reduces the analysis of a complicated multivariate stochastic model to the consideration of that model’s associated univariate full conditional distributions.)
