OFDM-FH自适应抗干扰技术研究
Research on Anti-Jamming of Adaptive OFDM Frequency Hopping
摘要
Abstract
An algorithm based on anti-jamming is proposed to solve the problem of jamming in the in-band of OFDM system in tactical communication.The algorithm combines the advantage of anti-jamming in OFDM system and frequency hopping system,which can sound the sub-channel quality and adaptively change the frequency-hopping pattern and sub-carriers resource allocation according to the sub-channel quality.This would avoid jamming,and provide the robustness to wideband communication system.The experimental results show that:under the different jamming source, compared to OFDM-FH system,the OFDM-FH adaptive system can improve 1-3dB performance.And to OFDM system,it can improve 3-7 dB performance.关键词
