Novel Matrix Singular Value Inequalities and Their Applications to Uncertain MIMO Channels
(2015)
Novel matrix singular value inequalities are established for a sum/product of three matrices. Their application to the uncertain (compound) multiple-input multiple-output (MIMO) channel subject to normed additive uncertainty ...
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 ...
Further results on optimal signaling over secure MIMO channels
(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 ...
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 ...
The capacity of unstable dynamical systems-interaction of control and information transmission
(Institute of Electrical and Electronics Engineers Inc., 2017)
Feedback capacity is extended beyond classical communication channels, to stochastic dynamical systems, which may correspond to unstable control systems or unstable communication channels, subject to average cost constraints ...
Optimal filtering over uncertain wireless communication channels
(2011)
In this letter, filtering over wireless communication channels subject to packet losses is considered. The packet losses are assumed to follow a Bernoulli distribution. The latter is interpreted as a special case of a ...
An Algorithm for Global Maximization of Secrecy Rates in Gaussian MIMO Wiretap Channels
(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 ...
Mutual information expansion for MIMO systems and capacity formulae at low SNR
(2011)
The paper introduces a new asymptotic series expansion for the mutual information of multiple-input multiple-output (MIMO) channels. The expansion approaches mutual information from below, and for low signal to noise ratio ...
