Ergodic capacity under channel distribution uncertainty
(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 ...

On optimal signaling over secure MIMO channels
(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
(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 Wiretap MIMO Channels
(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 ...
