On Source Coding for Distributed Temperature Sensing with Shift-Invariant Geometries

Robert Konsbruck

We study the source coding problem in sensor networks deployed to monitor the evolution of spatio-temporal temperature distributions. The sensors sample the temperature field, quantize the samples and transmit the encoded samples through digital channels t ...

Channel State Feedback Over the MIMO-MAC

Krishna Kumar

In order to exploit the full multiplexing gain of multi-antenna multi-user downlink schemes, accurate channel state information at the transmitter (i.e., at the base station) is required. We consider the design of a closed-loop channel state information fe ...

In-place transformations with applications to encoding and decoding various classes of codes

Mohammad Amin Shokrollahi

In an encoder for encoding symbols of data using a computing device having memory constraints, a method of performing a transformation comprising loading a source block into memory of the computing device, performing an intermediate transformation of less ...

Strategies for Delay-Limited Source-Channel Coding

Marius Kleiner

In point-to-point source-channel communication with a fidelity criterion and a transmission cost constraint, the region of achievable cost and fidelity pairs is completely characterized by Shannon's separation theorem. However, this is in general only true ...

Transmission of Correlated Information Sources with Network Coding

Pascal Frossard, Nikolaos Thomos, Hyung Gon Park

This paper addresses the problem of the distributed delivery of correlated data sources with help of network coding. Network coding provides an alternative to routing algorithms and offers improved system performance, robustness and throughput, with no nee ...

Polar Codes are Optimal for Lossy Source Coding

Rüdiger Urbanke

We consider lossy source compression of a binary symmetric source using polar codes and the low-complexity successive encoding algorithm. It was recently shown by Arikan that polar codes achieve the capacity of arbitrary symmetric binary-input discrete mem ...

Distributed Successive Approximation Coding using Broadcast Advantage: the Two-Encoder Case

Martin Vetterli, Guillermo Barrenetxea Kobas, Zichong Chen

Traditional distributed source coding rarely considers the possible link between separate encoders. However, the broadcast nature of wireless communication in sensor networks provides a free gossip mechanism which can be used to simplify encoding/decoding ...

A Simple Converse of Burnashev's Reliability Function

Bixio Rimoldi, Emre Telatar, Peter Allan Berlin

In a remarkable paper published in 1976, Burna- shev determined the reliability function of variable-length block codes over discrete memoryless channels (DMCs) with feedback. Subsequently, an alternative achievability proof was obtained by Yamamoto and It ...
