Study of Multiuser Scheduling Based on User Satisfaction for MU-MIMO Systems
Ahmed M. Nor, Lukas T. N. Landau, E. Veronica Belmega +1
Scheduling in multiuser multiple input multiple output (MU-MIMO) systems is essential for efficient resource allocation and overall performance enhancement. In this work, a multius…
Fast Optimization with Zeroth-Order Feedback in Distributed, Multi-User MIMO Systems
Olivier Bilenne, Panayotis Mertikopoulos, E. Veronica Belmega
In this paper, we develop a gradient-free optimization methodology for efficient resource allocation in Gaussian MIMO multiple access channels. Our approach combines two main ingre…
Distributed stochastic optimization via matrix exponential learning
Panayotis Mertikopoulos, E. Veronica Belmega, Romain Negrel +1
In this paper, we investigate a distributed learning scheme for a broad class of stochastic optimization problems and games that arise in signal processing and wireless communicati…
Learning to be green: robust energy efficiency maximization in dynamic MIMO-OFDM systems
Panayotis Mertikopoulos, E. Veronica Belmega
In this paper, we examine the maximization of energy efficiency (EE) in next-generation multi-user MIMO-OFDM networks that evolve dynamically over time - e.g. due to user mobility,…
Enabling Data Exchange in Interactive State Estimation under Privacy Constraints
E. Veronica Belmega, Lalitha Sankar, H. Vincent Poor
Data collecting agents in large networks, such as the electric power system, need to share information (measurements) for estimating the system state in a distributed manner. Howev…
Transmit without regrets: Online optimization in MIMO-OFDM cognitive radio systems
Panayotis Mertikopoulos, E. Veronica Belmega
In this paper, we examine cognitive radio systems that evolve dynamically over time due to changing user and environmental conditions. To combine the advantages of orthogonal frequ…
