      Minimizing outage probability for a class of MIMO channels 

      Charalambous, Charalambos D.; Ioannou, I. (2009)
      In this paper we investigate the outage probability of Multiple-Input Multiple-Output (MIMO) channels, when the probability distribution of the channel gains is not completely known to the transmitter and receiver. The ...

      On optimal signaling over secure MIMO channels 

      Loyka, S.; Charalambous, Charalambos D. (2012)
      Optimal signalling over the wire-tap MIMO Gaussian channel is studied under the total transmit power constraint. A direct proof of the necessary condition of optimality (signaling on the positive directions of the difference ...

      Outage capacity and probability for a class of MIMO channels 

      Ioannou, I.; Charalambous, Charalambos D. (2010)
      This paper is concerned with outage capacity and probability of Multiple-Input Multiple-Output (MIMO) systems for a class of channel distributions. The results illustrate how outage probability and capacity degrade as a ...

      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 ...

      Rank-deficient solutions for optimal signaling over secure MIMO channels 

      Loyka, S.; Charalambous, Charalambos D. (Institute of Electrical and Electronics Engineers Inc., 2014)
      Capacity-achieving signaling strategies for the Gaussian wiretap MIMO channel are investigated without the degradedness assumption. In addition to known solutions, a number of new rank-deficient solutions for the optimal ...
