this is program about satelit constalation

用来估计dynanmic copula的参数和copula vine中的相关参数，并进行拟合。(Used to estimate the parameters in dynanmic copula parameters and a copula vine, and fitting.)

电力系统潮流计算程序，C++程序，电力系统稳态时的小作业(Power flow calculation program, small operations C++ procedures, steady state power system)

在matlab7.8版本上编译通过。 利用matlab的滤波器工具箱函数实现对直扩扩频通信过程的仿真模型，可以简单设定功率控制，多径传输，多值干扰等过程。(This program is compiled successfully in Matlab7.8 platform. With the matlab Filter Toolbox funtion to simulate the process of spread spectrum transmission. The simple option such as power control,multiprocess and multiaddress nterference can be set in this program。)

此方法是求互信息，方法很好哦，希望大家下载！谢谢(this is very good file hope you get it)
