摘要
论文基于白化滤波器与子空间码辅助技术,对低频通信中带内干扰频域抑制展开研究,并仿真分析其在单频干扰、多频干扰和窄带干扰下的误码率性能。仿真结果表明,子空间码辅助技术适用于抑制单频干扰和多频干扰,而白化滤波器技术能够有效抑制窄带干扰。
Based on the whitening filter and subspace code assisted technology,this paper studies the frequency domain suppression of in-band interference in low-frequency communication,and simulates and analyzes its bit error rate performance under single-frequency interference,multi-frequency interference and narrowband interference.The simulation results show that the subspace code assist technology is suitable for suppressing single-frequency interference and multi-frequency interference,while the whitening filter technology can effectively suppress narrow-band interference.
