      General non-stationary models for short-term and long-term fading channels 

      Charalambous, Charalambos D.; Menemenlis, N. (Institute of Electrical and Electronics Engineers Inc., 2000)
      This paper discusses the use of stochastic differential equations to model signal envelope variations over large areas, which are subject to long-term fading effects from the transmitter to local areas, followed by short-term ...

      Joint preprocessing and feedback strategies for perfectly reconstructing equalizers 

      Touri, R.; Voulgaris, P.; Hadjicostis, Christoforos N. (2008)
      In this paper we consider the transmission of discrete-valued data via a communication channel that is subject to (additive) noise with a known upper bound on its magnitude but otherwise completely unrestricted and unknown ...

      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 ...

      Statistical analysis of the received signal over multipath fading channels via generalization of shot-noise 

      Charalambous, Charalambos D.; Menemenlis, M. (2001)
      This paper is a continuation of the companion paper [1], in which multipath fading channels (MFC) are formulated as generalizations of the shot-noise analysis in investigating the statistical properties of wireless channels ...

      Stochastic channel modeling for ad hoc wireless networks 

      Olama, M. M.; Djouadi, S. M.; Charalambous, Charalambos D. (2006)
      Due to nodes mobility and environmental changes in mobile ad hoc networks, the ad hoc channel is time varying and subject to fading. As a consequence of these variations, the statistical characteristics of the received ...

      A Systems Approach to Channel Equalization 

      Venkatesh, S.; Voulgaris, P.; Hadjicostis, Christoforos N. (2003)
      In this paper we present a control theoretic frame-work for channel equalization. Channel equalization methods are used to mitigate the effects of inter-symbol interference (ISI). Traditional methods, maximize the signal ...
