有关AM调制的实例，简洁实用，很有针对性，已经运行通过(Examples of the AM modulation, simple and practical, very targeted, has been running through the)

pfx格式或者p121格式文件的解析器， PfxTest文件 使用一个BASE64编码的P12文件字节数组，默认密码123456，CERT为三级证书，使用BC库作为JCE实现(pfx test java code , decrypt a p12 format file (such as .pfx,.p12 file) the pfxtest use a sampled p12 file which is base64 encoded, the pfx password is 123456, and is an three level cert chain, the resolve use the BC lib ——the JCE open implemention)

AITKEN S INTERPOLATION Aitken s procedure yields systematically and successively better interpolation polynomials corresponding to successively higher order truncation of Newton s divided difference formula. Given a set of x and corresponding f(x), estimate f1(x1) f1= aitkenInterp(x,f,x1) f = corresponding function of x f1= corresponding function of x1

求点d1到直线d2-d3的距离，并画线。范例： [d dl]=find_dl([2 1],[8 3],[4 7]) 则 dl=[6 5]。(Example: [d dl] = find_dl ([2 1], [8 3], [4 7]) if dl = [6 5].)

适用于多种分布（正态、Gamma、瑞利、对数高斯等）的样本数据拟合及画图函数的matlab代码(Matlab code to plot and fit a histogram of data with a certain distribution including normal, Gamma, Reilgh, log-normal, etc.)

在光通信系统中的低密度奇偶校验码的性能仿真中，利用该软件可以检测校验矩阵中是否含有4环和6环，并且可以检测出4环和6环出现次数最多的点。(Performance Simulation LDPC in an optical communication system, the use of the software can detect whether a check matrix containing 4 and 6 ring ring, and can detect the highest number of points 4 and 6 ring ring appears.)

This paper proposes a novel and computationally efficient global I< optimization method based on swarm ntelligence for locating ti nodes in a WSN environment. The mean squared range error of a all neighbouring anchor nodes is taken as the objective function d for this non linear optimization problem. The Particle Swarm c Optimization (PSO) is a high performance stochastic global b optimization tool that ensures the minimization of the objective a function,

This is a matlab code for BPSK, 16QAM and 32QAM demodulation
