      Further results on optimal signaling over secure MIMO channels 

      Loyka, S.; Charalambous, Charalambos D. (2013)
      Optimal signalling over the wire-tap MIMO Gaussian channel is studied under the total transmit power constraint. The recent results are extended in several directions, including a rank-deficient solution for the optimal ...

      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 ...

      Optimal signaling for secure communications over Gaussian MIMO wiretap channels 

      Loyka, S.; Charalambous, Charalambos D. (2016)
      Optimal signaling over the Gaussian multiple-input multiple-output wire-tap channel is studied under the total transmit power constraint. A closed-form solution for an optimal transmit covariance matrix is obtained when ...

      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 ...

      Rank-Deficient Solutions for Optimal Signaling over Wiretap MIMO Channels 

      Loyka, S.; Charalambous, Charalambos D. (2016)
      Capacity-achieving signaling strategies for the Gaussian wiretap multiple-input multple-output (MIMO) channel are investigated without the degradedness assumption. In addition to known solutions, a number of new rank-deficient ...
