$CSIsnoop$ : Inferring Channel State Information in Multi-User MIMO WLANs
Sign Up to like & getrecommendations! Published in 2019 at "IEEE/ACM Transactions on Networking"
DOI: 10.1109/tnet.2018.2884174
Abstract: Channel state information (CSI) has been proposed to enhance physical layer security by functioning as a shared secret between a transmitter and a receiver, because it decorrelates over half wavelength distances and cannot be predicted… read more here.

Mitigating Smart Jammers in Multi-User MIMO
Sign Up to like & getrecommendations! Published in 2022 at "IEEE Transactions on Signal Processing"
DOI: 10.1109/tsp.2023.3246226
Abstract: Wireless systems must be resilient to jamming attacks. Existing mitigation methods based on multi-antenna processing require knowledge of the jammer's transmit characteristics that may be difficult to acquire, especially for smart jammers that evade mitigation… read more here.
