Distributed source coding
WebDistributed source coding in a sensor network. The first attempts to design quantizers for Wyner–Ziv (WZ) coding—that is, lossy source coding of a single instance of directly observed data with side information at the decoder—were inspired by the information-theoretic proofs. WebJan 6, 2024 · Wyner-Ziv (WZ) coding, or source coding with side information at the decoder, can be considered as both a generalized and a degenerated case of Slepian-Wolf (SW) coding. It generalizes SW coding from the lossless to the lossy case, which is similar to the generalization of the classic source coding problem to the rate-distortion problem. …

WebWe propose a distributed quasi-cyclic low-density parity-check (QC-LDPC) coded spatial modulation (D-QC-LDPCC-SM) scheme with source, relay and destination nodes. At the source and relay, two distinct QC-LDPC codes are used. The relay chooses partial source information bits for further encoding, and a distributed code corresponding to each … WebOct 4, 2013 · The statistical description of the source sequences can be of a much more general nature, there can be more than two correlated source sequences, and the …
Distributed source coding (DSC) is an important problem in information theory and communication. DSC problems regard the compression of multiple correlated information sources that do not communicate with each other. By modeling the correlation between multiple sources at the decoder side together … See more In 1973, David Slepian and Jack Keil Wolf proposed the information theoretical lossless compression bound on distributed compression of two correlated i.i.d. sources X and Y. After that, this bound was extended to cases … See more Deterministic model Probabilistic model See more The syndrome approach can still be used for more than two sources. Consider $${\displaystyle a}$$ binary sources of length- See more The information theoretical lossless compression bound on DSC (the Slepian–Wolf bound) was first purposed by David Slepian and Jack Keil Wolf in terms of entropies of correlated information sources in 1973.
