Remote Source Coding under Gaussian Noise : Dueling Roles of Power and Entropy Power
Krishnan Eswaran, Michael Gastpar
The distributed remote source coding (so-called CEO) problem is studied in the case where the underlying source, not necessarily Gaussian, has finite differential entropy and the o…
Secrecy via Sources and Channels
Vinod M. Prabhakaran, Krishnan Eswaran, Kannan Ramchandran
Alice and Bob want to share a secret key and to communicate an independent message, both of which they desire to be kept secret from an eavesdropper Eve. We study this problem of s…
Bits through ARQs
Krishnan Eswaran, Michael Gastpar, Kannan Ramchandran
A fundamental problem in dynamic frequency reuse is that the cognitive radio is ignorant of the amount of interference it inflicts on the primary license holder. A model for such a…
Zero-rate feedback can achieve the empirical capacity
Krishnan Eswaran, Anand D. Sarwate, Anant Sahai +1
The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boos…
