Performance Analysis under IRS-User Association for Distributed IRSs Assisted MISO Systems
Hibatallah Alwazani, Qurrat-Ul-Ain Nadeem, Anas Chaaban
Distributed intelligent reflecting surfaces (IRSs) deployed in multi-user wireless communication systems promise improved system performance. However, the signal-to-interference-pl…
Intelligent Reflecting Surface Enabled Random Rotations Scheme for the MISO Broadcast Channel
Qurrat-Ul-Ain Nadeem, Alessio Zappone, Anas Chaaban
The current literature on intelligent reflecting surface (IRS) focuses on optimizing the IRS phase shifts to yield coherent beamforming gains, under the assumption of perfect chann…
Channel Estimation for Distributed Intelligent Reflecting Surfaces Assisted Multi-User MISO Systems
Hibatallah Alwazani, Qurrat-Ul-Ain Nadeem, Anas Chaaban
Intelligent reflecting surfaces (IRSs)-assisted wireless communication promises improved system performance, while posing new challenges in channel estimation (CE) due to the passi…
Opportunistic Beamforming using an Intelligent Reflecting Surface Without Instantaneous CSI
Qurrat-Ul-Ain Nadeem, Anas Chaaban, Merouane Debbah
While intelligent reflecting surface (IRS) assisted wireless communication has emerged as an important research paradigm, channel state information (CSI) acquisition remains a crit…
Intelligent Reflecting Surface Assisted MISO Downlink: Channel Estimation and Asymptotic Analysis
Bayan Al-Nahhas, Qurrat-Ul-Ain Nadeem, Anas Chaaban
This work makes the preliminary contribution of studying the asymptotic performance of a multi-user intelligent reflecting surface (IRS) assisted-multiple-input single-output (MISO…
Intelligent Reflecting Surface Assisted Multi-User MISO Communication: Channel Estimation and Beamforming Design
Qurrat-Ul-Ain Nadeem, Hibatallah Alwazani, Abla Kammoun +3
The concept of reconfiguring wireless propagation environments using intelligent reflecting surfaces (IRS)s has recently emerged, where an IRS comprises of a large number of passiv…
