Approximate lower bounds for rate-distortion in compressive sensing systems
We attempt to quantify the possible gains that can be achieved by examining a rate-distortion competition between a conventional and a compressive sampling solution to data rate r...

PhotoGeo: A Self-Organizing System for Personal Photo Collections
Nowadays the photo-capturing devices are no longer limited to digital cameras but include mobile phones, PDAs and others. This is leading to a new problem: a very large number of ...

Transaction Rate Limiters for Peer-to-Peer Systems
We introduce transaction rate limiters, new mechanisms that limit (probabilistically) the maximum number of transactions a user of a peer-to-peer system can do in any given period...

Discrete-Rate Adaptive Multiuser Scheduling for MIMO-OFDM Systems
Abstract— In this paper, we present a multiuser scheduling technique for the MIMO-OFDM system over multipath frequency-selective fading channels to exploit the multiuser, space a...

On Multi-User Gain in MIMO Systems with Rate Constraints
—In this paper, we study the advantages of multi-user concurrent transmission, measured using the multi-user gain (MUG), in multiple-input multiple-output (MIMO) systems with rat...
