Iterative Marginal Maximum Likelihood DOD and DOA Estimation for MIMO Radar in the Presence of SIRP Clutter
Bruno Mériaux, Xin Zhang, Mohammed Nabil El Korso +1
The spherically invariant random process (SIRP) clutter model is commonly used in scenarios where the radar clutter cannot be correctly modeled as a Gaussian process. In this short…
Interference Exploitation-based Hybrid Precoding with Robustness Against Phase Errors
Ganapati Hegde, Christos Masouros, Marius Pesavento
Hybrid analog-digital precoding significantly reduces the hardware costs in massive MIMO transceivers when compared to fully-digital precoding at the expense of increased transmit…
Energy Consumption Optimization in Mobile Communication Networks
Florian Bahlke, Marius Pesavento
This work addresses the challenge of minimizing the energy consumption of a wireless communication network by joint optimization of the base station transmit power and the cell act…
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…
Joint Antenna Selection and Phase-Only Beamforming Using Mixed-Integer Nonlinear Programming
Tobias Fischer, Ganapati Hegde, Frederic Matter +3
In this paper, we consider the problem of joint antenna selection and analog beamformer design in downlink single-group multicast networks. Our objective is to reduce the hardware…
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…
Optimized Cell Planning for Network Slicing in Heterogeneous Wireless Communication Networks
Florian Bahlke, Oscar D. Ramos-Cantor, Steffen Henneberger +1
We propose a cell planning scheme to maximize the resource efficiency of a wireless communication network while considering quality-of-service requirements imposed by different mob…
