IRS-Assistance with Outdated CSI: Element subset selection for secrecy performance enhancement
Chu Li, Aydin Sezgin
In this work, we investigate the secrecy performance in an intelligent reflecting surface (IRS)-assisted downlink system. In particular, we consider a base station (BS)-side IRS an…
On the Impact of Oscillator Phase Noise in an IRS-assisted MISO TDD System
Chu Li, Aydin Sezgin, Zhu Han
In this work, we study the impact of the multiplicative phase noise in an IRS-assisted system. We consider an IRS-assisted system with multiplicative phase noise both at the BS and…
Spoofing attack detection in dynamic channels with imperfect CSI
Chu Li, Aydin Sezgin
Recently, channel state information (CSI) at the physical-layer has been utilized to detect spoofing attacks in wireless communications. However, due to hardware impairments and co…
Kalman filter based MIMO CSI phase recovery for COTS WiFi devices
Chu Li, Jeremy Brauer, Aydin Sezgin +1
Recently channel state information (CSI) measurements from commercial multi input multi output (MIMO) WiFi systems have been ubiquitously used for different wireless sensing applic…
