TDD系统大气波导干扰研究与应对

Research and response on atmospheric duct interference in TDD system

本文围绕大气波导的成因和特点,结合对TDD(Time Division Duplexing,时分双工)通信系统的干扰影响,从大气波导干扰的理论依据、干扰应对措施两个角度出发,对大气波导干扰背景下的TDD通信系统无线网络优化开展了研究分析,指出了在大气波导干扰背景下,针对性开展干扰查找、干扰对抗(时域、频域和空域)及分阶段实施的方法,为大气波导干扰背景下TDD通信系统的无线优化提供重要指导。

This paper fi rst focuses on the causes and characteristics of atmospheric duct,and then combining with the interference effects on Time Division Duplex(TDD)communication system,this paper carries out research and analysis on the wireless network optimization for TDD system from two aspects:the theory basis of atmospheric duct interference,and the methods for interference suppression.This paper fi nds out the approaches of targeted interference search,anti-interference(time domain,frequency domain and space domain)and phased ones under the background of atmospheric duct interference,which provide important guidance on the wireless network optimization for TDD system in this case.
