Intelligent Reflecting Surface Aided Vehicular Communications [PDF]
2020 IEEE Globecom Workshops (GC Wkshps, 2020 We investigate the use of an intelligent reflecting surface (IRS) in a millimeter-wave (mmWave) vehicular communication network. An intelligent reflecting surface consists of passive elements, which can reflect the incoming signals with adjustable phase shifts. By properly tuning the phase shifts we can improve link performance.

Massive MIMO Communication With Intelligent Reflecting Surface
IEEE Transactions on Wireless Communications, 2023 This paper studies the feasibility of deploying intelligent reflecting surfaces (IRSs) in massive MIMO (multiple-input multiple-output) systems to improve the performance of users in the service dead zone. To reduce the channel training overhead, we advocate a novel protocol for the uplink communication in the IRS-assisted massive MIMO systems.

Federated Learning via Intelligent Reflecting Surface [PDF]
IEEE Transactions on Wireless Communications, 2022 Over-the-air computation (AirComp) based federated learning (FL) is capable of achieving fast model aggregation by exploiting the waveform superposition property of multiple access channels. However, the model aggregation performance is severely limited by the unfavorable wireless propagation channels.

Covert Transmission Assisted by Intelligent Reflecting Surface [PDF]
IEEE Transactions on Communications, 2021 Covert transmission is studied for an intelligent reflecting surface (IRS) aided communication system, where Alice aims to transmit messages to Bob without being detected by the warden Willie. Specifically, an IRS is used to increase the data rate at Bob under a covert constraint.

Feasibility of a Plasma-Based Intelligent Reflective Surface
IEEE Access, 2022 Gaseous Plasma Antennas are devices in which an ionized gas (i.e., plasma) is exploited to transmit and receive Electromagnetic waves. Their main advantage over metallic systems is the possibility to reconfigure the antenna performance (e.g., radiation pattern) by electronically varying the plasma parameters (e.g., density).

SWIPT With Intelligent Reflecting Surfaces Under Spatial Correlation [PDF]
IEEE Wireless Communications Letters, 2021 Intelligent reflecting surfaces (IRSs) can be beneficial to both information and energy transfer, due to the gains achieved by their multiple elements. In this work, we deal with the impact of spatial correlation between the IRS elements, in the context of simultaneous wireless information and power transfer.
