Performance Analysis for Multi-User Holographic MIMO Downlink with Matched Filter Precoding
Gayathri Shekar, Saman Atapattu, Prathapasinghe Dharmawansa +1
Holographic MIMO (HMIMO) has emerged as a promising solution for future wireless systems by enabling ultra-dense, spatially continuous antenna deployments. While prior studies have…
Eigenvalue-Based Detection in MIMO Systems for Integrated Sensing and Communication
Alex Obando, Saman Atapattu, Prathapasinghe Dharmawansa +2
This paper considers a MIMO Integrated Sensing and Communication (ISAC) system, where a base station simultaneously serves a MIMO communication user and a remote MIMO sensing recei…
Opportunistic Beamforming and Dynamic Scheduling for Multi-User MIMO-ISAC Systems
Tharaka Perera, Saman Atapattu, Chathuranga Weeraddana +1
This research presents a novel framework integrating Flexible-Duplex (FlexD) and Integrated Sensing and Communications (ISAC) technologies to address the challenges of spectrum eff…
Detection of Signals in Colored Noise: Leading Eigenvalue Test for Non-central -matrices
Prathapasinghe Dharmawansa, Saman Atapattu, Jamie Evans +1
This paper investigates the signal detection problem in colored noise with an unknown covariance matrix. In particular, we focus on detecting an unknown non-random signal by capita…
