A Heuristic-Integrated DRL Approach for Phase Optimization in Large-Scale RISs
Wei Wang, Peizheng Li, Angela Doufexi +1
Optimizing discrete phase shifts in large-scale reconfigurable intelligent surfaces (RISs) is challenging due to their non-convex and non-linear nature. In this letter, we propose…
An Achievability Bound for Variable-Length Stop-Feedback Coding over the Gaussian Channel
Ioannis Papoutsidakis, Robert J. Piechocki, Angela Doufexi
Feedback holds a pivotal role in practical communication schemes, even though it does not enhance channel capacity. Its main attribute includes adaptability in transmission that al…
Integer-Based Pattern Synthesis for Asymmetric Multi-Reflection RIS
Wei Wang, Angela Doufexi, Mark A Beach
This study delves into the radiation pattern synthesis of reconfigurable intelligent surfaces (RIS) / reflection metasurfaces. Through superimposing multiple single-reflection prof…
DRL-Based Sidelobe Suppression for Multi-focus Reconfigurable Intelligent Surface
Wei Wang, Peizheng Li, Angela Doufexi +1
Reconfigurable intelligent surface (RIS) technology is receiving significant attention as a key enabling technology for 6G communications, with much attention given to coverage inf…
Joint User Scheduling, Power Allocation, and Rate Control for MC-RSMA in URLLC Services
Xiaoyu Ou, Shuping Dang, Zhihan Ren +1
This paper investigates the resource management problem in multi-carrier rate-splitting multiple access (MC-RSMA) systems with imperfect channel state information (CSI) and success…
A DRL-based Reflection Enhancement Method for RIS-assisted Multi-receiver Communications
Wei Wang, Peizheng Li, Angela Doufexi +1
In reconfigurable intelligent surface (RIS)-assisted wireless communication systems, the pointing accuracy and intensity of reflections depend crucially on the 'profile,' represent…
