Book Synopsis An Energy Efficient Rate Adaptive Distributed Source Coding by : Kwame Porter-Robinson
Download or read book An Energy Efficient Rate Adaptive Distributed Source Coding written by Kwame Porter-Robinson and published by . This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current strategies for estimating correlation among multiple sources typically require an unsupported degree of network bandwidth or significant computational resources required by the receiver. A novel strategy that does not suffer from these weaknesses is desirable and is a current topic of research in distributed source coding theory. A novel source correlation algorithm, RSWITCH, is presented that both minimizes network bandwidth and required computational resources beyond that given by the state of the art.

Download or read book Source Coding written by Thomas Wiegand and published by Now Publishers Inc. This book was released on 2011-01-05 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Source Coding is the first part of the two-part monograph Fundamentals of Source and Video Coding by Wiegand and Schwarz. It is devoted to the fundamental subject of source coding. Source Coding is a standalone text and also forms the basis for the second part, which describes the application of sources coding techniques to video coding. Based on a simple and accessible presentation of the fundamentals of information and rate distortion theory, the authors describe the subjects of entropy coding and quantization as well as predictive and transform coding. All relevant source coding results that are required for the understanding of today's video compression algorithms are established. The emphasis is on source coding techniques that have become relevant for video coding in recent years. To illustrate the concepts and efficiency of the basic sources coding techniques, the authors provide numerous examples and experimental results for simple model sources. In addition to widely known results, the text also offers some elements that are new or rarely covered in references on source coding today, which include: Huffman coding for variable-length symbol sequences and PIPE coding, scalar quantization in combination with advanced entropy coding techniques, a simple model for the rate distortion performance of entropy-constrained scalar quantization for Gaussian sources that is valid over the entire bit rate range, a proof for the optimality of the Karhunen-Loève transform for Gaussian sources. Source Coding is suitable as a primary text for courses on this subject. It can also be used as a resource for teaching and as a comprehensive reference for professional engineers and academic researches.
Book Synopsis Source Coding Theory by : Robert M. Gray
Download or read book Source Coding Theory written by Robert M. Gray and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Source coding theory has as its goal the characterization of the optimal performance achievable in idealized communication systems which must code an information source for transmission over a digital communication or storage channel for transmission to a user. The user must decode the information into a form that is a good approximation to the original. A code is optimal within some class if it achieves the best possible fidelity given whatever constraints are imposed on the code by the available channel. In theory, the primary constraint imposed on a code by the channel is its rate or resolution, the number of bits per second or per input symbol that it can transmit from sender to receiver. In the real world, complexity may be as important as rate. The origins and the basic form of much of the theory date from Shan non's classical development of noiseless source coding and source coding subject to a fidelity criterion (also called rate-distortion theory) [73] [74]. Shannon combined a probabilistic notion of information with limit theo rems from ergodic theory and a random coding technique to describe the optimal performance of systems with a constrained rate but with uncon strained complexity and delay. An alternative approach called asymptotic or high rate quantization theory based on different techniques and approx imations was introduced by Bennett at approximately the same time [4]. This approach constrained the delay but allowed the rate to grow large.
Book Synopsis Distributed Lossy Source Coding Using BCH-DFT Codes by : Mojtaba Vaezi
Download or read book Distributed Lossy Source Coding Using BCH-DFT Codes written by Mojtaba Vaezi and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Distributed source coding, separate encoding (compression) and joint decoding of statistically dependent sources, arises in an increasing number of applications like sensor networks and multiview video coding. Many of those applications are highly interactive, requiring the development of low-delay, energy-limited communication and computing schemes. Currently, this compression is performed by using capacity-approaching binary channel codes. As a natural extension, distributed lossy source coding is realized by cascading a quantizer and Slepian-Wolf coding in the binary domain. Despite big strides in practical distributed source coding techniques, this problem is still demanding in terms of processing power, bandwidth, and delay.In this dissertation, we develop a new framework for distributed lossy source coding, in which we use real-number codes for binning. Specifically, we use a class of Bose-Chaudhuri-Hocquenghem (BCH) codes in the real/complex field known as the discrete Fourier transform (DFT) codes. Contrary to the conventional scheme, we first compress the continuous-valued sources and then quantize them. The new scheme exploits the correlation between continuous-valued sources, rather than quantized ones, which is more accurate. Also, by using short BCH-DFT codes, it reduces the complexity and delay and offers the potential to avoid the problems of the conventional quantization and binning approach, with relatively simple encoder/decoder.We propose both syndrome- and parity-based schemes, and we extend the parity-based scheme to distributed joint source-channel coding based on a single DFT code. Further, to adapt to uncertainty in the degree of statistical dependence between the sources, we construct rate-adaptive BCH-DFT codes. This allows the encoder to switch flexibly between encoding sample rates, if the degree of statistical dependence varies. The construction of rate-adaptive codes is based on transmission of additional syndrome samples and a simple extension of the subspace-based decoding.Another major contribution of this dissertation is to generalize the encoding/decoding of BCH-DFT codes. We prove that the parity frequencies of a BCH-DFT code, or equivalently the zeros of codewords in the frequency domain, are not required to be adjacent; we provide the decoding algorithm as well. This offers flexibility in constructing BCH-DFT codes and further improvement in the decoding which can be exploited in channel coding as well." --
Book Synopsis Distributed Coding of Spatio-temporally Correlated Sources by : Ankur Saxena
Download or read book Distributed Coding of Spatio-temporally Correlated Sources written by Ankur Saxena and published by ProQuest. This book was released on 2008 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies certain problems in distributed coding of correlated sources. The first problem considers the design of efficient coders in a robust distributed source coding scenario. Here, the information is encoded at independent terminals and transmitted across separate channels, any of which may fail. This scenario subsumes a wide range of source and source-channel coding/quantization problems, including multiple descriptions and the CEO problem. A global optimization algorithm based on deterministic annealing is proposed for the joint design of all the system components. The proposed approach avoids many poor local optima, is independent of initialization, and does not make any simplifying assumption on the underlying source distribution.
Book Synopsis Source and Channel Coding by : John B. Anderson
Download or read book Source and Channel Coding written by John B. Anderson and published by Springer Science & Business Media. This book was released on 1991-09-30 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: oW should coded communication be approached? Is it about prob H ability theorems and bounds, or about algorithms and structures? The traditional course in information theory and coding teaches these together in one course in which the Shannon theory, a probabilistic the ory of information, dominates. The theory's predictions and bounds to performance are valuable to the coding engineer, but coding today is mostly about structures and algorithms and their size, speed and error performance. While coding has a theoretical basis, it has a practical side as well, an engineering side in which costs and benefits matter. It is safe to say that most of the recent advances in information theory and coding are in the engineering of coding. These thoughts motivate the present text book: A coded communication book based on methods and algorithms, with information theory in a necessary but supporting role. There has been muchrecent progress in coding, both inthe theory and the practice, and these pages report many new advances. Chapter 2 cov ers traditional source coding, but also the coding ofreal one-dimensional sources like speech and new techniques like vector quantization. Chapter 4 is a unified treatment of trellis codes, beginning with binary convolu tional codes and passing to the new trellis modulation codes.
Book Synopsis Recursive Source Coding by : G. Gabor
Download or read book Recursive Source Coding written by G. Gabor and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spreading of digital technology has resulted in a dramatic increase in the demand for data compression (DC) methods. At the same time, the appearance of highly integrated elements has made more and more com plicated algorithms feasible. It is in the fields of speech and image trans mission and the transmission and storage of biological signals (e.g., ECG, Body Surface Mapping) where the demand for DC algorithms is greatest. There is, however, a substantial gap between the theory and the practice of DC: an essentially nonconstructive information theoretical attitude and the attractive mathematics of source coding theory are contrasted with a mixture of ad hoc engineering methods. The classical Shannonian infor mation theory is fundamentally different from the world of practical pro cedures. Theory places great emphasis on block-coding while practice is overwhelmingly dominated by theoretically intractable, mostly differential predictive coding (DPC), algorithms. A dialogue between theory and practice has been hindered by two pro foundly different conceptions of a data source: practice, mostly because of speech compression considerations, favors non stationary models, while the theory deals mostly with stationary ones.
