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…
End-to-end Learning of Probabilistic and Geometric Constellation Shaping with Iterative Receivers
Harindu Jayarathne, Dileepa Marasinghe, Nandana Rajatheva +1
An end-to-end learning method for constellation shaping with a shaping-encoder assisted transceiver architecture is presented. The shaping encoder, which produces shaping bits with…
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…
Max-Min Fairness for Stacked Intelligent Metasurface-Assisted Multi-User MISO Systems
Nipuni Ginige, Prathapasinghe Dharmawansa, Arthur Sousa de Sena +3
Stacked intelligent metasurface (SIM) is an emerging technology that uses multiple reconfigurable surface layers to enable flexible wave-based beamforming. In this paper, we focus…
