Energy-Efficient Multi-Cell Multigroup Multicasting with Joint Beamforming and Antenna Selection
Oskari Tervo, Le-Nam Tran, Harri Pennanen +3
This paper studies the energy efficiency and sum rate trade-off for coordinated beamforming in multi-cell multi-user multigroup multicast multiple-input single-output systems. We f…
Successive Convex Approximation Algorithms for Sparse Signal Estimation with Nonconvex Regularizations
Yang Yang, Marius Pesavento, Symeon Chatzinotas +1
In this paper, we propose a successive convex approximation framework for sparse optimization where the nonsmooth regularization function in the objective function is nonconvex and…
Architectures and Key Technical Challenges for 5G Systems Incorporating Satellites
A. Guidotti, A. Vanelli-Coralli, M. Conti +10
Satellite Communication systems are a promising solution to extend and complement terrestrial networks in unserved or under-served areas. This aspect is reflected by recent commerc…
Energy efficiency optimization in MIMO interference channels: A successive pseudoconvex approximation approach
Yang Yang, Marius Pesavento, Symeon Chatzinotas +1
In this paper, we consider the (global and sum) energy efficiency optimization problem in downlink multi-input multi-output multi-cell systems, where all users suffer from multi-us…
Signal Processing for High Throughput Satellite Systems: Challenges in New Interference-Limited Scenarios
Ana I. Perez-Neira, Miguel Angel Vazquez, Sina Maleki +2
The field of satellite communications is enjoying a renewed interest in the global telecom market, and very high throughput satellites (V/HTS), with their multiple spot-beams, are…
