In this paper, the redundancy of both variable and fixed rate Slepian–Wolf coding is considered. Given any jointly memoryless source-side information pair with finite alphabet, the redundancy of variable rate Slepian–Wolf coding of  with decoder only side information depends on both the block length and the decoding block error probability , and is defined as the difference between the minimum...

In this paper, it is shown that each Slepian–Wolf coding problem is related to a dual channel coding problem in the sense that the sphere packing exponents, random coding exponents, and correct decoding exponents in these two problems are mirror-symmetrical to each other. This mirror symmetry is interpreted as a manifestation of the linear codebook-level duality between Slepian–Wolf coding and ...

In this paper, we give a distributed joint source channel coding scheme for arbitrary correlated sources for arbitrary point in the Slepian-Wolf rate region, and arbitrary link capacities using LDPC codes. We consider the Slepian-Wolf setting of two sources and one destination, with one of the sources derived from the other source by some correlation model known at the decoder. Distributed enco...

A multiple access source code (MASC) is a source code designed for the following network configuration: a pair of correlated information sequences {Xi}lm_, and {x}lm_, is drawn i.i.d. according to joint probability mass function (p.m.f.) p ( z , y); the encoder for each source operates without knowledge of the other source; the decoder jointly decodes the encoded bit streams from both sources. ...

|Universal coding problem for the system of Slepian and Wolf (the SW-system) has rst been investigated by Csisz ar and Korner. They considered the correlated memoryless sources, and established a universally attainable error exponent as a function of rate pair (R1;R2) that is positive whenever (R1; R2) is an inner point of the admissible rate region of the SW-system, which is speci ed dependin...

The estimation of potential fields such as the gravitational or magnetic potential at the surface of a spherical planet from noisy observations taken at an altitude over an incomplete portion of the globe is a classic example of an ill-posed inverse problem. Here we show that the geodetic estimation problem has deep-seated connections to Slepian’s spatiospectral localization problem on the sphe...
