Outage and Capacity Comparisons For Ground Relaying Systems Using Stochastic Geometry
Spyridon Evangelatos, Aris L. Moustakas, Andreas Polydoros
Concurrent cooperative transmission for relaying purposes in mobile communication networks is relevant in current institutional systems with limited infrastructure, and and may be…
The Shannon's mutual information of a multiple antenna time and frequency dependent channel: an ergodic operator approach
Walid Hachem, Aris Moustakas, Leonid Pastur
Consider a random non-centered multiple antenna radio transmission channel. Assume that the deterministic part of the channel is itself frequency selective, and that the random mul…
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…
