Satellite Link Analysis and Calculation Software Design

摘要

Satellite communication system is a typical digital communication system whose communication reliability index is ultimately determined by the system error rate. In the codec mode, modulation and demodulation system components are used to determine the link carrier to noise ratio to determine the system's bit error rate. This paper first gives the threshold of the system carrier to noise ratio and link parameters calculation method, the use of Visual Studio independent development of link calculation software, link calculation, then it calculates a satellite communication system link margin.
