An abstract channel specification and an algorithm implementing it using Java sockets
(2008)Models and specifications can be used in the design of distributed applications to formally reason about their safety properties. However, the benefits of using formal methods are often negated by the ad hoc process of ...

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 ...

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 ...

Comparison of techniques used for mapping parallel algorithms to message-passing multiprocessors
(IEEE, 1994)This paper presents a comparison study of popular clustering and mapping heuristics which are used to map task-flow graphs to message-passing multiprocessors. To this end, we use task-graphs which are representative of ...

Control of discrete-time partially-observed jump linear systems over causal communication systems
(2006)We consider the problem of control of discrete-time partially-observed jump linear system over a noisy causal communication channel. Necessary conditions for observability and stabilizability in probability and r-th mean ...

Control of jump linear systems over jump communication channels - Source-channel matching approach
(2007)The control of partially observed jump linear systems over jump communication channels is investigated when the Plant State Information (I*SI) and the Channel Slate Information (CSI) are present at the transmitter and the ...

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 ...
