Recovery under Side Constraints
Khaled Ardah, Martin Haardt, Tianyi Liu +3
This paper addresses sparse signal reconstruction under various types of structural side constraints with applications in multi-antenna systems. Side constraints may result from pr…
Coordinated Hybrid Precoding for Interference Exploitation in Heterogeneous Networks
Ganapati Hegde, Christos Masouros, Marius Pesavento
We consider a downlink multiuser massive MIMO system comprising multiple heterogeneous base stations with hybrid precoding architectures. To enhance the energy efficiency of the ne…
Inexact Block Coordinate Descent Algorithms for Nonsmooth Nonconvex Optimization
Yang Yang, Marius Pesavento, Zhi-Quan Luo +1
In this paper, we propose an inexact block coordinate descent algorithm for large-scale nonsmooth nonconvex optimization problems. At each iteration, a particular block variable is…
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…
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…
