Bandwidth and power allocation for cooperative strategies in Gaussian relay networks
Abstract-- In a relay network with a single sourcedestination pair, we examine the achievable rates with amplifyand-forward (AF) relaying strategy. Motivated by applications in sen...

Average case analysis of multichannel sparse recovery using convex relaxation
This paper considers recovery of jointly sparse multichannel signals from incomplete measurements. Several approaches have been developed to recover the unknown sparse vectors from...

Capacity of Channels With Action-Dependent States
We consider channels with action-dependent states: Given the message to be communicated, the transmitter chooses an action sequence that affects the formation of the channel state...

On the efficiency of shortened cyclic single-burst-correcting codes
Shortened cyclic codes that are capable of correcting up to a single burst of errors are considered. The efficiency of such codes has been analized by how well they approximate the...

Lossy source compression using low-density generator matrix codes: analysis and algorithms
We study the use of low-density generator matrix (LDGM) codes for lossy compression of the Bernoulli symmetric source. First, we establish rigorous upper bounds on the average dist...

Wideband fading channel capacity with training and partial feedback
We consider the capacity of a wideband fading channel with partial feedback, subject to an average power constraint. A doubly block Rayleigh fading model is assumed with finite co...

Periodic orbits and equilibria in glass models for gene regulatory networks
Abstract--Glass models are frequently used to model gene regulatory networks. A distinct feature of the Glass model is that its dynamics can be formalized as paths through multi-di...

Tighter bounds on the capacity of finite-state channels via Markov set-chains
The theory of Markov set-chains is applied to derive upper and lower bounds on the capacity of finite-state channels that are tighter than the classic bounds by Gallager. The new ...

On the capacity achieving covariance matrix for Rician MIMO channels: an asymptotic approach
In this contribution, the capacity-achieving input covariance matrices for coherent blockfading correlated MIMO Rician channels are determined. In contrast with the Rayleigh and u...

QR decomposition of Laurent polynomial matrices sampled on the unit circle
Abstract--We consider Laurent polynomial (LP) matrices defined on the unit circle of the complex plane. QR decomposition of an LP matrix A(s) yields QR factors Q(s) and R(s) that, ...
