A Framework for Optimizing Multi-cell NOMA: Delivering Demand with Less Resource
Lei You, Lei Lei, Di Yuan +3
Non-orthogonal multiple access (NOMA) allows multiple users to simultaneously access the same time-frequency resource by using superposition coding and successive interference canc…
Low Complexity Symbol-Level Design for Linear Precoding Systems
Jevgenij Krivochiza, Ashkan Kalantari, Symeon Chatzinotas +1
The practical utilization of the symbol-level precoding in MIMO systems is challenging since the implementation of the sophisticated optimization algorithms must be done with reaso…
Constrained Bayesian Active Learning of Interference Channels in Cognitive Radio Networks
Anestis Tsakmalis, Symeon Chatzinotas, Björn Ottersten
In this paper, a sequential probing method for interference constraint learning is proposed to allow a centralized Cognitive Radio Network (CRN) accessing the frequency band of a P…
Distributed Optimization for Coordinated Beamforming in Multi-Cell Multigroup Multicast Systems: Power Minimization and SINR Balancing
Oskari Tervo, Harri Pennanen, Dimitrios Christopoulos +2
This paper considers coordinated multicast beamforming in a multi-cell multigroup multiple-input single-output system. Each base station (BS) serves multiple groups of users by for…
Resource Optimization with Load Coupling in Multi-cell NOMA
Lei You, Di Yuan, Lei Lei +3
Optimizing non-orthogonal multiple access (NOMA) in multi-cell scenarios is much more challenging than the single-cell case because inter-cell interference must be considered. Most…
Energy-Efficient Joint Unicast and Multicast Beamforming with Multi-Antenna User Terminals
Oskari Tervo, Le-Nam Tran, Symeon Chatzinotas +2
This paper studies energy-efficient joint transmit and receive beamforming in multi-cell multi-user multiple-input multiple-output systems. We consider conventional network energy…
