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…
A CNN-based End-to-End Learning for RIS-assisted Communication System
Nipuni Ginige, Nandana Rajatheva, Matti Latva-aho
Reconfigurable intelligent surface (RIS) is an emerging technology that is used to improve the system performance in beyond 5G systems. In this letter, we propose a novel convoluti…
Efficient Channel Prediction for Beyond Diagonal RIS-Assisted MIMO Systems with Channel Aging
Nipuni Ginige, Arthur Sousa de Sena, Nurul Huda Mahmood +2
Novel reconfigurable intelligent surface (RIS) architectures, known as beyond diagonal RISs (BD-RISs), have been proposed to enhance reflection efficiency and expand RIS capabiliti…
Untrained DNN for Channel Estimation of RIS-Assisted Multi-User OFDM System with Hardware Impairments
Nipuni Ginige, K. B. Shashika Manosha, Nandana Rajatheva +1
Reconfigurable intelligent surface (RIS) is an emerging technology for improving performance in fifth-generation (5G) and beyond networks. Practically channel estimation of RIS-ass…
Admission Control in 5G Networks for the Coexistence of eMBB-URLLC Users
Nipuni Uthpala Ginige, K. B. Shashika Manosha, Nandana Rajatheva +1
In this paper, we consider the problem of admission control in 5G networks where enhanced mobile broadband (eMBB) users and ultra-reliable low-latency communication (URLLC) users a…
