摘要 线性调频(LFM或Chirp)干扰是一种典型的非平稳宽带干扰信号。分析了线性调频干扰对OFDM系统的误码率性能的影响。仿真结果表明线性调频干扰可有效地降低OFDM系统的性能,性能恶化程度与干扰功率、调频率、扫频周期等参数有关。 Linear Frequency Modulated(LFM or Chirp) signal is a typical nonstationary signal.This paper mainly analyzes the effect of OFDM performance in LFM interference channel.The simulation shows that LFM interference deteriorates the OFDM performance badly,and that the deterioration degree depends on the jamming power,chirp rate and sweeping period.
