Common Reconstructions in the Successive Refinement Problem with Receiver Side Information
Badri N. Vellambi, Roy Timo
We study a variant of the successive refinement problem with receiver side information where the receivers require identical reconstructions. We present general inner and outer bou…
A Rate-Distortion Approach to Caching
Roy Timo, Shirin Saeedi Bidokhti, Michèle Wigger +1
This paper takes a rate-distortion approach to understanding the information-theoretic laws governing cache-aided communications systems. Specifically, we characterise the optimal…
A Multiway Relay Channel with Balanced Sources
Lawrence Ong, Roy Timo
We consider a joint source-channel coding problem on a finite-field multiway relay channel, and we give closed-form lower and upper bounds on the optimal source-channel rate. These…
Complete Interference Mitigation Through Receiver-Caching in Wyner's Networks
Michèle Wigger, Roy Timo, Shlomo Shamai
We present upper and lower bounds on the per-user multiplexing gain (MG) of Wyner's circular soft-handoff model and Wyner's circular full model with cognitive transmitters and rece…
Noisy Broadcast Networks with Receiver Caching
Shirin Saeedi Bidokhti, Michèle Wigger, Roy Timo
We study noisy broadcast networks with local cache memories at the receivers, where the transmitter can pre-store information even before learning the receivers' requests. We mostl…
Conferencing in Wyner's Asymmetric Interference Network: Effect of Number of Rounds
Michèle Wigger, Roy Timo, Shlomo Shamai
Our goal is to study the effect of the number of conferencing rounds on the capacity of large interference networks. We do this at hand of the per-user multiplexing gain (MG) of Wy…
