Distributed Hypothesis Testing with Variable-Length Coding
Sadaf Salehkalaibar, Michele Wigger
This paper characterizes the optimal type-II error exponent for a distributed hypothesis testing-against-independence problem when the \emph{expected} rate of the sensor-detector l…
On the Capacity of MIMO Optical Wireless Channels
Longguang Li, Stefan M. Moser, Ligong Wang +1
This paper studies the capacity of a general multiple-input multiple-output (MIMO) free-space optical intensity channel under a per-input-antenna peak-power constraint and a total…
Age of Information Aware Cache Updating with File- and Age-Dependent Update Durations
Haoyue Tang, Philippe Ciblat, Jintao Wang +2
We consider a system consisting of a library of time-varying files, a server that at all times observes the current version of all files, and a cache that at the beginning stores t…
Distributed Hypothesis Testing: Cooperation and Concurrent Detection
Pierre Escamilla, Michèle Wigger, Abdellatif Zaidi
A single-sensor two-detectors system is considered where the sensor communicates with both detectors and Detector 1 communicates with Detector 2, all over noise-free rate-limited l…
Multiplexing Gain Region of Sectorized Cellular Networks with Mixed Delay Constraints
Homa Nikbakht, Michèle Wigger, Shlomo Shamai
The sectorized hexagonal model with mixed delay constraints is considered when both neighbouring mobile users and base stations can cooperate over rate-limited links. Each message…
A Fundamental Storage-Communication Tradeoff for Distributed Computing with Straggling Nodes
Qifa Yan, Michèle Wigger, Sheng Yang +1
Placement delivery arrays for distributed computing (Comp-PDAs) have recently been proposed as a framework to construct universal computing schemes for MapReduce-like systems. In t…
