      An Algorithm for Global Maximization of Secrecy Rates in Gaussian MIMO Wiretap Channels 

      Loyka, S.; Charalambous, Charalambos D. (2015)
      Optimal signaling for secrecy rate maximization in Gaussian MIMO wiretap channels is considered. While this channel has attracted a significant attention recently and a number of results have been obtained, including the ...

      Convex design control for practical nonlinear systems 

      Baldi, S.; Michailidis, I.; Kosmatopoulos, E. B.; Papachristodoulou, A.; Ioannou, Petros A. (2014)
      This paper describes a new control scheme for approximately optimal control (AOC) of nonlinear systems, convex control design (ConvCD). The key idea of ConvCD is to transform the approximate optimal control problem into a ...

      Ergodic capacity under channel distribution uncertainty 

      Loyka, S.; Charalambous, Charalambos D.; Ioannou, I. (Institute of Electrical and Electronics Engineers Inc., 2014)
      The impact of channel distribution uncertainty on the performance of fading channels is studied. The compound capacity of a class of ergodic fading channels subject to channel distribution uncertainty is obtained, for ...

      Nonlinear control of large scale complex systems using convex optimization tools and self-adaptation 

      Baldi, S.; Kosmatopoulos, E. B.; Ampountolas, Konstantinos; Rovas, D.; Papachristodoulou, A.; Ioannou, Petros A. (2011)
      Based on recent advances on convex design for Large-Scale Control Systems (LSCSs) and robust and efficient LSCS self-tuning/adaptation, a methodology is proposed in this paper which aims at providing an integrated LSCS-design, ...

      Outage probability under channel distribution uncertainty 

      Ioannou, I.; Charalambous, Charalambos D.; Loyka, S. (2012)
      Outage probability and capacity of a class of block-fading MIMO channels are considered under partial channel distribution information. Specifically, the channel or its distribution is not known but the latter is known to ...

      Outage probability under channel distribution uncertainty 

      Ioannou, I.; Charalambous, Charalambos D.; Loyka, S. (2011)
      Outage probability of a class of block-fading (MIMO) channels is considered under channel distribution uncertainty, when the channel or its distribution are not known but the latter is known to belong to a class of ...

      A scalable iterative convex design for nonlinear systems 

      Baldi, S.; Ioannou, Petros A.; Kosmatopoulos, E. B. (2012)
      A recently developed control scheme for approximately optimal control of nonlinear systems is the so-called Convex Control Design (ConvCD) methodology, that transforms the control problem of generic nonlinear systems into ...
