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…
Deep Unfolding of Iteratively Reweighted ADMM for Wireless RF Sensing
Udaya S. K. P. Miriya Thanthrige, Peter Jung, Aydin Sezgin
We address the detection of material defects, which are inside a layered material structure using compressive sensing based multiple-input and multiple-output (MIMO) wireless radar…
Synergistic Benefits in IRS- and RS-enabled C-RAN with Energy-Efficient Clustering
Kevin Weinberger, Alaa Alameer Ahmad, Aydin Sezgin +1
The potential of intelligent reflecting surfaces (IRSs) is investigated as a promising technique for enhancing the energy efficiency of wireless networks. Specifically, the IRS ena…
Full-Duplex meets Reconfigurable Surfaces: RIS-assisted SIC for Full-Duplex Radios
Simon Tewes, Markus Heinrichs, Paul Staat +2
Reconfigurable intelligent surfaces (RIS) are a key enabler of various new applications in 6G smart radio environments. By utilizing an RIS prototype system, this paper aims to enh…
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…
