this is the program for cross layer estimate in matlab environment

A new technique of free-space simulation has been developed for solving unbounded electromagnetic problems with the finite-difference time-domain method.

信道估计很好的matlab代码，大家快来下载啊啊 啊 啊(Channel estimation good matlab code, everyone be quick to download )

用simulink的实现的 非常难找的系统的封装与发送回主程序的方法(Simulink realization is very difficult to find the package and sent back to the main program )

Linear control systems

the code file that is uploded is harmfreq file

进行航天器轨道运算经常用到的函数，包括坐标转换，经纬度转换，二体运动，轨道要素计算等等(For spacecraft orbit operations frequently used functions, including coordinate conversion, latitude and longitude conversion, two-body movement, and so calculated orbital elements)
