by Robert M. Gray, Source Coding Theory Books available in PDF, EPUB, Mobi Format. Download Source Coding Theory books, 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)  . 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 . This approach constrained the delay but allowed the rate to grow large.

by George C. Clark Jr., Error Correction Coding For Digital Communications Books available in PDF, EPUB, Mobi Format. Download Error Correction Coding For Digital Communications books, Error-correction coding is being used on an almost routine basis in most new communication systems. Not only is coding equipment being used to increase the energy efficiency of communication links, but coding ideas are also providing innovative solutions to many related communication problems. Among these are the elimination of intersymbol interference caused by filtering and multipath and the improved demodulation of certain frequency modulated signals by taking advantage of the "natural" coding provided by a continuous phase. Although several books and nu merous articles have been written on coding theory, there are still noticeable deficiencies. First, the practical aspects of translating a specific decoding algorithm into actual hardware have been largely ignored. The information that is available is sketchy and is widely dispersed. Second, the information required to evaluate a particular technique under situations that are en countered in practice is available for the most part only in private company reports. This book is aimed at correcting both of these problems. It is written for the design engineer who must build the coding and decoding equipment and for the communication system engineer who must incorporate this equipment into a system. It is also suitable as a senior-level or first-year graduate text for an introductory one-semester course in coding theory. The book U"Ses a minimum of mathematics and entirely avoids the classical theorem/proof approach that is often seen in coding texts.
by Branka Vucetic, Space Time Coding Books available in PDF, EPUB, Mobi Format. Download Space Time Coding books, The capacity of wireless data communications is lagging behind demands due to unsatisfactory performance of the existing wireless networks, such as low data rates, low spectral efficiency and low quality of service. Space-time coding is an effective transmit diversity technique to combat fading in wireless communications. Space-time codes are a highly bandwidth-efficient approach to signalling within wireless communication that takes advantage of the spatial dimension by transmitting a number of data streams using multiple co-located antennas. There are various approaches to the coding structures, including space-time trellis coded modulation, space-time turbo codes and also layered architectures. The central issue in all these various coding structures is the exploitation of multipath effects in order to achieve very high spectral efficiencies. The spectral efficiencies of traditional wireless systems range between 1-5bps/sec/Hz but by using space-time techniques spectral efficiencies of 20-40bps/sec/Hz have been possible. Hence, space-time coding enables an increase in capacity by an order of magnitude. This is the main reason why space-time codes have been included in the standards for the third generation wireless communication systems and ultimately why Space-time Coding will be in great demand by individuals within industry and academia. The comprehensive understanding of space-time coding is essential in the implementation of 3G, and as the only title currently available, Space-Time Coding will be the standard text for Researchers, telecommunication engineers and network planners, academics and undergraduate/postgraduate students, telecommunications managers and consultants.
by Donna Avila-Weil, Independent Medical Coding Books available in PDF, EPUB, Mobi Format. Download Independent Medical Coding books, There is an enormous and growing demand for skilled medical coders, creating a severe shortage in a large variety of coding situations. Demand greater than supply can result in excellent compensation for those on the supply side. So, how do you determine if medical coding is the profession for you? If you are already a medical coder, how do you identify and evaluate the rapidly expanding variety of opportunities open to you? INDEPENDENT MEDICAL CODING, 2nd edition: The Comprehensive Guidebook for Career Success as a Medical Coder (just published by Rayve Productions) provides answers to these questions and many more, such as What is Coding?; Are You Ready to Go Solo?; What is the Future of Coding in Health Care? The 448-page book also gives extensive information regarding Medical Coding Education and Experience; Continuing Professional Education; Becoming Credentialed; Medical Transcriptionists as Coding Specialists; Salary Projections Based on Survey Data; Types of Coding Systems; Establishing Your Independent Coding Business; Alternative Careers for the Health Care Coding Specialist; Establishing Fees; Marketing Tips; Contracts and Independent Contractors; Building a Successful Coding/Consulting Business; Professional Ethics; Finances; and much more, including descriptions of the authors' favorite references and resources and the appendix's twenty-three exhibits of helpful forms and documents.

by A. Houghton, Error Coding For Engineers Books available in PDF, EPUB, Mobi Format. Download Error Coding For Engineers books, Error Coding for Engineers provides a useful tool for practicing engineers, students, and researchers, focusing on the applied rather than the theoretical. It describes the processes involved in coding messages in such a way that, if errors occur during transmission or storage, they are detected and, if necessary, corrected. Very little knowledge beyond a basic understanding of binary manipulation and Boolean algebra is assumed, making the subject accessible to a broad readership including non-specialists. The approach is tutorial: numerous examples, illustrations, and tables are included, along with over 30 pages of hands-on exercises and solutions. Error coding is essential in many modern engineering applications. Engineers involved in communications design, DSP-based applications, IC design, protocol design, storage solutions, and memory product design are among those who will find the book to be a valuable reference. Error Coding for Engineers is also suitable as a text for basic and advanced university courses in communications and engineering.
