Book Description
200 brand new compelling and addictive word and number puzzles from The Times. Appearing daily in the newspaper, Codeword is the cracking alternative to Su Doku and Crosswords. The concept is simple: each number represents a letter, so, starting with the solved letters, use your logic and vocabulary to reveal more letters, form words, and then crack the code! The most difficult puzzles for top solvers contain no solved letters so you need to employ all your logical strategies to crack those. The Codeword series is so popular because you don't need any prior knowledge, unlike a crossword. You can just pick up a pen and get puzzling. It steadily increases your vocabulary, as the difficulty slowly grows as you progress through the book, and even though you'll be working your brain, it's the perfect way to unwind.

Quasi-orthogonal Space-time Block Code

Quasi-orthogonal Space-time Block Code PDF Author: Yong Liang Guan
Publisher: World Scientific
ISBN: 1908979100
Category : Technology & Engineering
Languages : en
Pages : 209

Book Description
Quasi-Orthogonal Space-Time Block Code presents an up-to-date, comprehensive and in-depth discussion of an important emerging class of space-time codes, called the Quasi-Orthogonal STBC (QO-STBC). Used in Multiple-Input Multiple-Output (MIMO) communication systems, they provide transmit diversity with higher code rates than the well-known orthogonal STBC (O-STBC), yet at lower decoding complexity than non-orthogonal STBC. This book will help readers gain a broad understanding of the fundamental principles as well as the state-of-the-art work in QO-STBC, thus enabling them to appreciate the roles of QO-STBC in future broadband wireless systems and to inspire further research./a

Fundamentals of Classical and Modern Error-Correcting Codes

Fundamentals of Classical and Modern Error-Correcting Codes PDF Author: Shu Lin
Publisher: Cambridge University Press
ISBN: 1009080563
Category : Technology & Engineering
Languages : en
Pages : 844

Book Description
Using easy-to-follow mathematics, this textbook provides comprehensive coverage of block codes and techniques for reliable communications and data storage. It covers major code designs and constructions from geometric, algebraic, and graph-theoretic points of view, decoding algorithms, error control additive white Gaussian noise (AWGN) and erasure, and dataless recovery. It simplifies a highly mathematical subject to a level that can be understood and applied with a minimum background in mathematics, provides step-by-step explanation of all covered topics, both fundamental and advanced, and includes plenty of practical illustrative examples to assist understanding. Numerous homework problems are included to strengthen student comprehension of new and abstract concepts, and a solutions manual is available online for instructors. Modern developments, including polar codes, are also covered.

Optical Code Division Multiple Access Communication Networks

Optical Code Division Multiple Access Communication Networks PDF Author: Hongxi Yin
Publisher: Springer Science & Business Media
ISBN: 3540684689
Category : Technology & Engineering
Languages : en
Pages : 399

Book Description
Optical code division multiple access (OCDMA) communication network technology will play an important role in future optical networks, such as optical access and metropolitan area networks. OCDMA technology can also be applied to implement optical signal multiplexing and label switching on backbone networks. Optical Code Division Multiple Access Communication Networks - Theory and Applications introduces the code theory of OCDMA, the methods and technologies of OCDMA encoding and decoding, the theory and methods of analyzing OCDMA systems with various receiver models and realizing multiple-class services with different bit rates and QoS. In addition, OCDMA network architectures, protocols and applications are discussed in detail. The up-to-date theoretical and experimental results on OCDMA systems and networks are also reported. A large number of encoding/decoding examples and many analysis and simulation results of code and system performances are given. It is a valuable text and/or reference book for postgraduates majoring in telecommunication and photonics to obtain a well-knit theoretical foundation and for engineers in R&D and management of optical communications. Dr. Yin is an Associate Professor of the School of Electronics Engineering and Computer Science at Peking University, China, and was a Visiting Research Fellow of Optoelectronics Research Centre (ORC) at University of Southampton, UK. Dr. Richardson is a Professor for optical communications and Deputy Director of ORC at University of Southampton, UK, and is responsible for much of the ORC's fiber related activities.
