Slepian-Wolf Coding for Intrusion Identification System of Digital Images

Analysis of Slepian Wolf Coding

Universal Incremental Slepian-Wolf Coding

We present a strategy for Slepian-Wolf coding when the joint distribution of the sources is unknown. The encoders use an incremental transmission policy, and the decoder a universal sequential decision test. We show that the decoder is able to decode shortly after the rates of transmission exceed the Slepian-Wolf bounds. The decoder then send an ACK back to the encoders, terminating transmissio...

Polar Codes for Nonasymmetric Slepian-Wolf Coding

A method to construct nonasymmetric distributed source coding (DSC) scheme using polar codes which can achieve any point on the dominant face of the Slepian–Wolf (SW) rate region for sources with uniform marginals is considered. In addition to nonasymmetric case, we also discuss and show explicitly how asymmetric and single source compression is done using successive cancellation (SC) polar dec...

Redundancy Rates of Slepian-Wolf Coding∗

The results of Shannon theory are asymptotic and do not reflect the finite codeword lengths used in practice. Recent progress in design of distributed source codes, along with the need for distributed compression in sensor networks, has made it crucial to understand how quickly distributed communication systems can approach their ultimate limits. Slepian and Wolf considered the distributed enco...

On the redundancy of Slepian--Wolf coding

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...
