Analysis and Simulation of OFDM Channel Estimation Error Under Pilot Jamming
Li Ha · Electronic Information Warfare Technology · 2014
Pilot jamming is a smart jamming method to OFDM systems. Aiming to MMSE channel 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 validates the theoretical derivation and demonstrates the pilot jamming is more efficient than the wideband barrage jamming.
