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…
Edge-Caching Wireless Networks: Performance Analysis and Optimization
Thang X. Vu, Symeon Chatzinotas, Bjorn Ottersten
Edge-caching has received much attention as an efficient technique to reduce delivery latency and network congestion during peak-traffic times by bringing data closer to end users.…
