Distributed Source Coding


Book Description

Distributed source coding is one of the key enablers for efficient cooperative communication. The potential applications range from wireless sensor networks, ad-hoc networks, and surveillance networks, to robust low-complexity video coding, stereo/Multiview video coding, HDTV, hyper-spectral and multispectral imaging, and biometrics. The book is divided into three sections: theory, algorithms, and applications. Part one covers the background of information theory with an emphasis on DSC; part two discusses designs of algorithmic solutions for DSC problems, covering the three most important DSC problems: Slepian-Wolf, Wyner-Ziv, and MT source coding; and part three is dedicated to a variety of potential DSC applications. Key features: Clear explanation of distributed source coding theory and algorithms including both lossless and lossy designs. Rich applications of distributed source coding, which covers multimedia communication and data security applications. Self-contained content for beginners from basic information theory to practical code implementation. The book provides fundamental knowledge for engineers and computer scientists to access the topic of distributed source coding. It is also suitable for senior undergraduate and first year graduate students in electrical engineering; computer engineering; signal processing; image/video processing; and information theory and communications.

Quantization and Transforms for Distributed Source Coding


Book Description

Experimental results for Wyner-Ziv quantization of Gaussian sources show consistency between the rate-distortion performance of the quantizers found by our extension of the Lloyd algorithm, and the performance predicted by the high-rate theory presented. Implementations of distributed transform codecs of clean Gaussian data and noisy images experimentally support the rate-distortion improvement due to the introduction of the discrete cosine transform, predicted in the theory developed.

Distributed Source Coding Over Wireless User Cooperation


Book Description

Distributed source coding (DSC) refers to the problem of compressing two or more physically-separated information sources, where the sources (e.g. sensors) send the (compressed) information to a central point (e.g. a monitoring station) without communicating to each other. Cooperative communication, also known as user cooperation or the relay channel problem, allows single-antenna users in a multi-user scenario to share antennas with each other to form a virtual multiple-antenna system. These two technologies, originated in the seventies, have caused a resurgence of interest in recent years. In this dissertation, we investigate these two technologies and try to apply distributed source coding into user cooperation. Three topics are studied: The first is to develop a new scheme to attack the noisy-channel Slepian-Wolf coding problem using serially concatenated codes (SCC). The advantage is two-fold: (i) separate refining of compression rate and error protection capability is made possible and (ii) many useful results about SCC can be used to achieve joint optimization. The second topic considers the design of two-user cooperation schemes by exploiting distributed source coding technologies. Two user cooperation schemes, Slepian-Wolf cooperation and Wyner-Ziv cooperation, are proposed, which exploit Slepian-Wolf coding and Wyner-Ziv coding, respectively. Possibly the first practical schemes that implement the idea of compress-and-forward, these schemes offer substantial gains over existing cooperative strategies especially when the inter-user channel is at outage. The third topic is to develop an extension for cooperative communication to High-Speed Packet Downlink Access (HSDPA) cellular system which increases both the overall cell capacity as well as coverage near the cell edge at a relatively low cost.
