卫星通信网络终端多载波干扰分析
Multi-carrier Interference Analysis of Satellite Communications Earth Terminal
摘要
Abstract
In the architecture of satellite communications earth terminal,every terminal can receive multi-carrier with different frequency at the same time,the factor such as the relative movement between the satellites and the terminals will produce frequency offset which can make interference among these carriers.This paper analyzes the effect of the frequency interference on the CIR,the loss of SNR and so on.The result of simulation shows that this interference will reduce the CIR of the system,the loss of SNR and BER of the system will be increased.The analysis provides a theoretical basis for the next step to eliminate inter-carrier interference.关键词
