      The capacity of unstable dynamical systems-interaction of control and information transmission 

      Charalambous, Charalambos D.; Kourtellaris, C. K.; Loyka, S.; Tzortzis, I. (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 ...

      On the channel capacity of wireless fading channels 

      Charalambous, Charalambos D.; Denic, S. (2002)
      The objectives of this paper are twofold. First, to point out the significance of certain results on stochastic processes in computing the channel capacity for flat fading wireless channels. Second, to design an optimal ...

      Robust capacity of white Gaussian noise channels with uncertainty 

      Charalambous, Charalambos D.; Denic, S. Z.; Djouadi, S. M. (2004)
      This paper concerns the problem of defining, and computing the channel capacity of a continuous time additive white Gaussian noise channel when the true frequency response of the channel is not completely known to the ...

      Upper and lower bounds on fsm switching activity 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2003)
      This paper obtains upper and lower bounds for the switching activity on the state lines of a finite state machine (FSM) that is driven with typical input sequences. By exploiting the symmetries between the Hamming distances ...
