差分编码的仿真程序，包含三个文件，给出了仿真性能！(Simulation of differential encoding process consists of three documents, the simulation performance!)

一个MATLAB程序包,用来产生随机的三维目标轨迹. 可以指定目标运行的高度范围, 速度范围和加速度范围. 希望对于研究目标跟踪的朋友有用. (A MATLAB package, used to generate three-dimensional random target trajectory. User can specify the range of hight, speed and acceleration of the target. Hope it s useful for friends studying target tracking.)

说明：  可计算关联维数，设置分形的参数，判断混沌状态(Calculate the correlation dimension, fractal parameters set to determine chaos)

数学建模的题目解析，胡乱拿来给大家分享，希望能对大家有帮助(The subject of mathematical modeling analysis, to be used indiscriminately to share, I hope you can help)

说明：  老外的一本绝版好书，绝版~有钱买不到的东西(Foreigners an out of print books, out of print ~ the things money can not buy)

ldpc码在AWGN信道下的性能仿真。包括geth.m,getG.m,H2G.m,decode.m,BER.m按传统的编码方案编码，生成H矩阵后转化为G矩阵，编码后送入高斯信道。仿真得到BER性能(ldpc codes in the AWGN channel performance simulation. Including geth.m, getG.m, H2G.m, decode.m, BER.m coded according to the traditional encoding scheme to generate H matrix is transformed into G matrix encoded into the Gaussian channel. Simulation, the BER performance)
