该程序实现了通信中16QAM的调制解调，并与理论误码率进行比较，证明仿真的正确性。(The program implements a 16QAM modulation and demodulation in a communication, with the theoretical bit error rate compared to prove the correctness of the simulation.)

this is a algoritm for cluster arrays data ,introducing the k cluster

An program for transmission line is given in this file.For Short the length is 80 km,for medium 80 to 250 km and for long transmission length is given by 250 km above.

matlab 顺序遍历二值图像 查找说有连通域，对不同的连通域使用不同编号(traversal order matlab binary image to find that there connected domain, for different connectivity domains using different numbers)

正交镜像滤波器的设计，从正交镜像滤波器的远离出发设计,而且从结果中观察其相位和幅度。( Design a two-channel QMF filter bank The four filters in the filter bank are based on a lowpass prototype H(z) which is designed by this procedure. The analysis filters are HL(z) and HH(z) and the synthesis filters are GL(z) and GH(z), HL(z) = H(z) HH(z) = H(-z) GL(z) = 2 H(z) GH(z) =-2 H(-z)

matlab6.0函数查询手册。使用非常方便，收录了matlab的大部分函数。(Manual query matlab6.0 function. Very convenient to use, includes most of the matlab function.)

arnold cat 映射实验，观察其迭代次数与置乱效果的关系，这是图像加密的典型算法(arnold cat mapping experiments to observe the number of iterations and the scrambling effect relationship, which is a typical image encryption algorithm)

contourlet工具包，属于超小波分析里头的contourlet变换的m文件(contourlet kits are super wavelet analysis inside the contourlet transform m file)

说明：  By using this we can implement a code division multiple access modem system
