Source-channel separation for two-way interactive communication with fidelity criteria
Mukul Agarwal
Consider the channel coding problem where two users are interacting in order to communicate an i.i.d. source X1 from User 1 to User 2 with distortion D1 and an i.i.d. source X2 fro…
Non-existence of certain kind of finite-letter mutual information characterization for a class of time-invariant Markoff channels
Mukul Agarwal
We provide a rigorous definition of a certain kind of characterization for capacity regions of a family of Markoff networks which is based on optimization problems resulting out of…
Rate-distortion functions of non-stationary Markoff chains and their block-independent approximations
Mukul Agarwal
It is proved that the limit of the normalized rate-distortion functions of block independent approximations of an irreducible, aperiodic Markoff chain is independent of the initial…
PSPACE hardness of approximating the capacity of Markoff channels with noiseless feedback
Mukul Agarwal
It will be proved that computing the capacity of a Markoff channel with noiseless feedback is PSPACE-hard.
Layered black-box, behavioral interconnection perspective and applications to the problem of communication with fidelity criteria, Part II: stationary sources satisfying ψ-mixing criterion
Mukul Agarwal, Sanjoy Mitter, Anant Sahai
Theorems from Part 1 of this paper are generalized to ψ-mixing sources in this paper. Application to Markoff chains and order m Markoff chains is presented. The main result is the…
Layered black-box, behavioral interconnection perspective and applications to the problem of communication with fidelity criteria, Part I: i.i.d. sources
Mukul Agarwal, Sanjoy Mitter, Anant Sahai
In this paper, the problem of communication over an essentially unknown channel, which is known to be able to communicate a source to a destination to within a certain distortion l…
A randomized covering-packing duality between source-coding and channel-coding
Mukul Agarwal, Sanjoy MItter
A randomized covering-packing duality between source and channel coding will be discussed by considering the source coding problem of coding a source with a certain distortion leve…
A universal, operational theory of unicast multi-user communication with fidelity criteria
Mukul Agarwal, Sanjoy Mitter, Anant Sahai
This is a three part paper. Optimality of source-channel separation for communication with a fidelity criterion when the channel is compound as defined by Csiszar and Korner in the…
Architecture for communication with a fidelity criterion in unknown networks
Mukul Agarwal, Sanjoy Mitter
We prove that in order to communicate independent sources (this is the unicast problem) between various users over an unknown medium to within various distortion levels, it is suff…
Equivalence perspectives in communication, source-channel connections and universal source-channel separation
Mukul Agarwal, Anant Sahai, Sanjoy Mitter
An operational perspective is used to understand the relationship between source and channel coding. This is based on a direct reduction of one problem to another that uses random…
