In estimation theory, mainly set-theoretic or stochastic uncertainty is considered. In some cases, especially when some statistics of a distribution are not known or additional stochastic information is used in a set-theoretic estimator, both types of uncertainty have to be considered. In this paper, two estimators that cope with combined stochastic and set-theoretic uncertainty are compared, namely...
Ever since the Federal Communications Commision (FCC) announced that it would open the television (TV) spectrum for opportunistic access, there has been an increased interest in industry as well as academia to come up with proposals that would fit the criteria laid by FCC. To this end, IEEE 802.22 Working Group (WG) is formulating the first worldwide standard for cognitive radio to operate in the...
Average consensus algorithms are protocols to compute the average value of all sensor measurements via near neighbors communications. They offer a natural tradeoff between the number of messages exchanged among terminals and the accuracy in the computation. Most of the models adopted for the message exchange in the literature, however, neither include explicit rate constraints nor explore the rate...
