Near optimal lossy source coding and compression-based denoising via Markov chain Monte Carlo
— We propose an implementable new universal lossy source coding algorithm. The new algorithm utilizes two wellknown tools from statistical physics and computer science: Gibbs sam...

Coordinated beamforming for the multi-cell multi-antenna wireless system
—In a conventional wireless cellular system, signal processing is performed on a per-cell basis; out-of-cell interference is treated as background noise. This paper considers the...

Distributed computation of a sparse cover in sensor networks without location information
— In this paper, we present a distributed algorithm for detecting redundancies in a sensor network with no location information. We demonstrate how, in the absence of localizatio...

A Modular Approach to Model Heterogeneous MPSoC at Cycle Level
This paper proposes a system-level cycle-based framework to model and design heterogeneous Multiprocessor Systems on-Chip (MPSoC), called GRAPES. The approach features flexibilit...
