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,…
Adaptive Power Allocation and Control in Time-Varying Multi-Carrier MIMO Networks
Ioannis Stiakogiannakis, Panayotis Mertikopoulos, Corinne Touati
In this paper, we examine the fundamental trade-off between radiated power and achieved throughput in wireless multi-carrier, multiple-input and multiple-output (MIMO) systems that…
In an Uncertain World: Distributed Optimization in MIMO Systems with Imperfect Information
Panayotis Mertikopoulos, Aris L. Moustakas
In this paper, we introduce a distributed algorithm that optimizes the Gaussian signal covariance matrices of multi-antenna users transmitting to a common multi-antenna receiver un…
Cost-Efficient Throughput Maximization in Multi-Carrier Cognitive Radio Systems
Salvatore D'Oro, Panayotis Mertikopoulos, Aris L. Moustakas +1
Cognitive radio (CR) systems allow opportunistic, secondary users (SUs) to access portions of the spectrum that are unused by the network's licensed primary users (PUs), provided t…
