Rethinking Passive RIS: Finite Blocklength Reliability Analysis Under Thermal Noise
Farjam Karim, Deepak Kumar, Prathapasinghe Dharmawansa +3
Short-packet communication alters the fundamental performance limits of reconfigurable intelligent surface (RIS)-assisted systems, making conventional analyses based on the infinit…
Passive RIS Is Not Silent: Revisiting Performance Limits Under Thermal Noise
Farjam Karim, Deepak Kumar, Prathapasinghe Dharmawansa +3
Reconfigurable intelligent surfaces (RISs) have emerged as a promising solution for enabling energy-efficient and flexible spectrum usage in wireless communication, particularly in…
Resource Allocation and AoI-Aware Detection for ISAC with Stacked Intelligent Metasurfaces
Elaheh Ataeebojd, Nhan Thanh Nguyen, Seonghoon Yoo +4
Stacked intelligent metasurfaces (SIMs) provide wave-domain degrees of freedom that can empower integrated sensing and communication (ISAC) through flexible beampattern synthesis a…
RSMA-Aided Full-Duplex Networks Under Imperfect CSI and SIC: Performance Evaluation
Farjam Karim, Nurul Huda Mahmood, Deepak Kumar +2
This work investigates a full-duplex (FD)-enhanced Rate-Splitting Multiple Access (RSMA) system under practical constraints, including imperfect channel state information (CSI) and…
Impact of CSIR, SIC, and Hardware Impairments on the Ergodic Rate of Downlink RSMA
Farjam Karim, Deepak Kumar, Prathapasinghe Dharmawansa +3
This work investigates the ergodic rate performance analysis of rate-splitting multiple access (RSMA) in a downlink communication system under practical impairments. Closed-form ex…
On the Robustness of RSMA to Adversarial BD-RIS-Induced Interference
Arthur S. de Sena, Jacek Kibilda, Nurul H. Mahmood +3
This article investigates the robustness of rate-splitting multiple access (RSMA) in multi-user multiple-input single-output (MISO) systems to interference attacks against channel…
