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…
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…
A Unified Successive Pseudo-Convex Approximation Framework
Yang Yang, Marius Pesavento
In this paper, we propose a successive pseudo-convex approximation algorithm to efficiently compute stationary points for a large class of possibly nonconvex optimization problems.…
An Online Parallel and Distributed Algorithm for Recursive Estimation of Sparse Signals
Yang Yang, Mengyi Zhang, Marius Pesavento +1
In this paper, we consider a recursive estimation problem for linear regression where the signal to be estimated admits a sparse representation and measurement samples are only seq…
