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. WebJun 5, 2024 · Abstract. Distributed source coding is the task of encoding an input in the absence of correlated side information that is only available to the decoder. Remarkably, …

Distributed source coding techniques for lossless compression of hyperspectral images. WebJul 1, 2024 · Distributed source coding (DSC) regards the compression of two or more statistically dependent source sequences which are not allowed to communicate with each other. Their compressed output are sent to a common decoder which utilizes the correlation among the sources to carry out joint decoding to reconstruct sources [1], [2]. Specifically ...
WebThe main challenge of source coding in a CPS is how to adapt the source coding scheme to the physical dynamics. In Section 8.3 we consider the point-to-point case, in which there is a single sensor and a single controller. Then the source coding is extended to the distributed case in Section 8.4, where we consider multiple sensors. Channel coding WebIn information theory and communication, the Slepian–Wolf coding, also known as the Slepian–Wolf bound, is a result in distributed source coding discovered by David Slepian and Jack Wolf in 1973. It is a method of theoretically coding two lossless compressed correlated sources.. Problem setup. Distributed coding is the coding of two, in this …
