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…
Power Minimizer Symbol-Level Precoding: A Closed-Form Sub-Optimal Solution
A. Haqiqatnejad, F. Kayhan, B. Ottersten
In this letter, we study the optimal solution of the multiuser symbol-level precoding (SLP) for minimization of the total transmit power under given signal-to-interference-plus-noi…
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…
Symbol-Level Precoding Design Based on Distance Preserving Constructive Interference Regions
Alireza Haqiqatnejad, Farbod Kayhan, Bjorn Ottersten
In this paper, we investigate the symbol-level precoding (SLP) design problem in the downlink of a multiuser multiple-input single-output (MISO) channel. We consider generic conste…
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…
