The Degraded Poisson Wiretap Channel
Amine Laourine, Aaron B. Wagner
Providing security guarantees for wireless communication is critically important for today's applications. While previous work in this area has concentrated on radio frequency (RF)…
Information embedding meets distributed control
Pulkit Grover, Aaron B. Wagner, Anant Sahai
We consider the problem of information embedding where the encoder modifies a white Gaussian host signal in a power-constrained manner to encode the message, and the decoder recove…
Erasure Multiple Descriptions
Ebad Ahmed, Aaron B. Wagner
We consider a binary erasure version of the n-channel multiple descriptions problem with symmetric descriptions, i.e., the rates of the n descriptions are the same and the distorti…
Rate Region of the Gaussian Scalar-Help-Vector Source-Coding Problem
Md Saifur Rahman, Aaron B. Wagner
We determine the rate region of the Gaussian scalar-help-vector source-coding problem under a covariance matrix distortion constraint. The rate region is achieved by a Gaussian ach…
Improved Source Coding Exponents via Witsenhausen's Rate
Benjamin G. Kelly, Aaron B. Wagner
We provide a novel upper-bound on Witsenhausen's rate, the rate required in the zero-error analogue of the Slepian-Wolf problem; our bound is given in terms of a new information-th…
On the Vacationing CEO Problem: Achievable Rates and Outer Bounds
Rajiv Soundararajan, Aaron B. Wagner, Sriram Vishwanath
This paper studies a class of source coding problems that combines elements of the CEO problem with the multiple description problem. In this setting, noisy versions of one remote…
