Approximation of Markov Processes by Lower Dimensional Processes via Total Variation Metrics
Ioannis Tzortzis, Charalambos D. Charalambous, Themistoklis Charalambous +2
The aim of this paper is to approximate a finite-state Markov process by another process with fewer states, called herein the approximating process. The approximation problem is fo…
Information Nonanticipative Rate Distortion Function and Its Applications
Photios A. Stavrou, Christos K. Kourtellaris, C. D. Charalambous
This paper investigates applications of nonanticipative Rate Distortion Function (RDF) in a) zero-delay Joint Source-Channel Coding (JSCC) design based on average and excess distor…
Capacity of Binary State Symmetric Channel with and without Feedback and Transmission Cost
Christos K. Kourtellaris, Charalambos D. Charalambous
We consider a unit memory channel, called Binary State Symmetric Channel (BSSC), in which the channel state is the modulo2 addition of the current channel input and the previous ch…
Applications of Information Nonanticipative Rate Distortion Function
Photios A. Stavrou, Christos K. Kourtellaris, Charalambos D. Charalambous
The objective of this paper is to further investigate various applications of information Nonanticipative Rate Distortion Function (NRDF) by discussing two working examples, the Bi…
