| Abstract: | The task the design method of link-budget for high-orbit satellite communication system are described, and the core calculation formulas of link-budget also given, and based on this, a link-budget software that could realize multi-parameter calculation is developed with the GUIDE module in MATLAB. This software makes up the defects of single function in most existing link-budget software, and realizes mutual operations among between transmission power, information rate and transmitting antenna aperture. The design ideas and methods of this software are expounded, its functions are described in detail. Finally the user interface of this software and a link-budget example completed with this software are also given in this paper. |
