      Comparative evaluation of despeckle filtering in ultrasound imaging of the carotid artery 

      Loizou, Christos P.; Pattichis, Constantinos S.; Christodoulou, Christodoulos I.; Istepanian, Robert Sh Habib; Pantzaris, Marios C.; Nicolaïdes, Andrew N. (2005)
      It is well-known that speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. The recent advancements in ultrasound instrumentation and portable ultrasound devices necessitate the need ...

      Nonanticipative rate distortion function and relations to filtering theory 

      Charalambous, Charalambos D.; Stavrou, P. A.; Ahmed, N. U. (2014)
      The relation between nonanticipative rate distortion function (RDF) and filtering theory is discussed on abstract spaces. The relation is established by imposing a realizability constraint on the reconstruction conditional ...

      Optimal filtering over uncertain wireless communication channels 

      Ma, X.; Djouadi, S. M.; Charalambous, Charalambos D. (2011)
      In this letter, filtering over wireless communication channels subject to packet losses is considered. The packet losses are assumed to follow a Bernoulli distribution. The latter is interpreted as a special case of a ...

      Time varying wireless channel modeling, estimation, identification, and power control from measurements 

      Olama, M. M.; Yanyan, L.; Djouadi, S. M.; Charalambous, Charalambos D. (2007)
      This paper is concerned with a time-varying wireless channel modeling, its parameter estimation, system identification, and optimal power control from measurement data. The channel model is represented in state space form, ...
