| 摘 要： | 导频干扰是针对正交频分(OFDM)系统的一种灵巧干扰方法。针对MMSE信道估计,推导了导频干扰下OFDM信道估计误差的统计分布,分析了相对于宽带阻塞干扰的优势。通过仿真验证了理论推导的正确性以及导频干扰相对于宽带阻塞干扰的高效性。

| Abstract: | Pilot jamming is a smart jamming method to OFDM systems. Aiming to MMSE chan- nel estimation, the statistical distribution of estimation error caused by pilot jamming is derived, and the advantage of pilot jamming over wideband barrage jamming is analyzed. Simulation vali- dates the theoretical derivation and demonstrates the pilot jamming is more efficient than the wideband barrage jamming. |
