Blind Channel Separation in Massive MIMO System under Pilot Spoofing and Jamming Attack
Ruohan Cao, Tan F. Wong, Hui Gao +2
We consider a channel separation approach to counter the pilot attack in a massive MIMO system, where malicious users (MUs) perform pilot spoofing and jamming attack (PSJA) in upli…
