Aggressive Non-Orthogonal Transmission with DFT-s-OFDM for Direct Device-to-Satellite Communications
Chathura Jayawardena, Konstantinos Nikitopoulos
Direct Device-to-Satellite (D2S) communications promise global connectivity to unmodified user equipment (UE), extending coverage beyond terrestrial networks. Realizing this promis…
Low-Complexity, Space Splitting-based User Selection in MU-MIMO for Massive Connectivity and AI-Native Traffic
João Paulo S. H. Lima, Marcin L. Filo, Chathura Jayawardena +1
The rise of Artificial Intelligence (AI)-driven services, machine-type communications, and massive Internet of Things (IoT) deployments is reshaping wireless traffic toward dense,…
NL-COMM-Sat: Breaking the Direct Device-to-Satellite Communication Barrier via "Aggressive" Non-Orthogonal Transmissions and Non-Linear Processing
Konstantinos Nikitopoulos, Chathura Jayawardena
Direct Device-to-Satellite (D2S) communications, which enable direct satellite connectivity with unmodified user equipment (UE), not only expand global coverage but also reshape th…
ViPer NL-COMM: Making Vector Perturbation Precoding Practical
Thomas James Thomas, George N. Katsaros, Chathura Jayawardena +1
Large MIMO systems rely on efficient downlink precoding to enhance data rates and improve connectivity through spatial multiplexing. However, currently employed linear precoding te…
NL-COMM: Enhanced Video Streaming via Advanced Non-Linear Processing
Marcin Filo, George N. Katsaros, Chathura Jayawardena +1
With video streaming now accounting for the majority of internet traffic, wireless networks face increasing demands, especially in densely populated areas where limited spectral re…
NL-COMM: Demonstrating Gains of Non-Linear Processing in Open-RAN Ecosystem
Chathura Jayawardena, Marcin Filo, George N. Katsaros +1
Multi-user multiple-input, multiple-output (MU-MIMO) designs can substantially increase wireless systems' achievable throughput and connectivity capabilities. However, existing MU-…
Ultra-Low-Complexity, Non-Linear Processing for MU-MIMO Systems
Chathura Jayawardena, Konstantinos Nikitopoulos
Non-linear detection schemes can substantially improve the achievable throughput and connectivity capabilities of uplink MU-MIMO systems that employ linear detection. However, the…
Towards Radio Designs with Non-Linear Processing for Next Generation Mobile Systems
Konstantinos Nikitopoulos, Marcin Filo, Chathura Jayawardena +1
MIMO mobile systems, with a large number of antennas at the base-station side, enable the concurrent transmission of multiple, spatially separated information streams and, therefor…
