Design and performance analysis of channel estimators under pilot spoofing attacks in multiple-antenna systems

23 Apr 2020 Darsena Donatella Gelli Giacinto Iudice Ivan Verde Francesco

In multiple antenna systems employing time-division duplexing, spatial precoder design at the base station (BS) leverages channel state information acquired through uplink pilot transmission, under the assumption of channel reciprocity. Malicious eavesdroppers can start pilot spoofing attacks to alter such design, so as to improve their eavesdropping performance in downlink... (read more)
