      Information states in stochastic control and filtering: a lie algebraic theoretic approach 

      Charalambous, Charalambos D.; Elliott, R. J. (2000)
      The purpose of this paper is twofold: i) to introduce the sufficient statistic algebra which is responsible for propagating the sufficient statistics, or information state, in the optimal control of stochastic systems and ...

      Minimax rate distortion for a class of sources 

      Rezaei, F.; Charalambous, Charalambos D.; Stavrou, P. A.; Kourtellaris, C. (2010)
      This paper deals with rate distortion or source coding with fidelity criterion, in measure spaces, for a class of source distributions. The class of source distributions is described by a relative entropy constraint set ...

      Minimizing outage probability for a class of MIMO channels 

      Charalambous, Charalambos D.; Ioannou, I. (2009)
      In this paper we investigate the outage probability of Multiple-Input Multiple-Output (MIMO) channels, when the probability distribution of the channel gains is not completely known to the transmitter and receiver. The ...
