Discrete-Time Frequency-Selective Rayleigh Fading Channel --- Impact of Correlated Scattering on Outage and Ergodic Capacity
Abstract— We consider a discrete-time frequencyselective block-fading channel with Rayleigh fading and correlated scattering. This is relevant in the area of UWB and if transceiv...

Time-Selective Convertible Undeniable Signatures
Undeniable signatures were introduced in 1989 by Chaum and van Antwerpen to limit the self-authenticating property of digital signatures. An extended concept – the convertible un...

Strategy Selection in Influence Diagrams using Imprecise Probabilities
This paper describes a new algorithm to solve the decision making problem in Influence Diagrams based on algorithms for credal networks. Decision nodes are associated to imprecise...

Region clustering based evaluation of multiple top-N selection queries
In many database applications, there are opportunities for multiple top-N queries to be evaluated at the same time. Often it is more cost effective to evaluate multiple such queri...

Diversity-Multiplexing Tradeoff in Selective-Fading MIMO Channels
— We establish the optimal diversity-multiplexing (DM) tradeoff of coherent time, frequency and time-frequency selective-fading MIMO channels and provide a code design criterion ...
