Phase-Locked Loops for Wireless Communications

Phase-Locked Loops for Wireless Communications

Donald R. Stephens

Springer
2001
sidottu
Phase-Locked Loops for Wireless Communications: Digitial, Analog and Optical Implementations, Second Edition presents a complete tutorial of phase-locked loops from analog implementations to digital and optical designs. The text establishes a thorough foundation of continuous-time analysis techniques and maintains a consistent notation as discrete-time and non-uniform sampling are presented. New to this edition is a complete treatment of charge pumps and the complementary sequential phase detector. Another important change is the increased use of MATLAB®, implemented to provide more familiar graphics and reader-derived phase-locked loop simulation. Frequency synthesizers and digital divider analysis/techniques have been added to this second edition. Perhaps most distinctive is the chapter on optical phase-locked loops that begins with sections discussing components such as lasers and photodetectors and finishing with homodyne and heterodyne loops. Starting with a historical overview, presenting analog, digital, and optical PLLs, discussing phase noise analysis, and including circuits/algorithms for data synchronization, this volume contains new techniques being used in this field. Highlights of the Second Edition: Development of phase-locked loops from analog to digital and optical, with consistent notation throughout; Expanded coverage of the loop filters used to design second and third order PLLs; Design examples on delay-locked loops used to synchronize circuits on CPUs and ASICS; New material on digital dividers that dominate a frequency synthesizer's noise floor. Techniques to analytically estimate the phase noise of a divider; Presentation of optical phase-locked loops with primers on the optical components and fundamentals of optical mixing; Section on automatic frequency control to provide frequency-locking of the lasers instead ofphase-locking; Presentation of charge pumps, counters, and delay-locked loops. The Second Edition includes the essential topics needed by wireless, optics, and the traditional phase-locked loop specialists to design circuits and software algorithms. All of the material has been updated throughout the book.

This is a contemporary reference work on phase-locked loops for wireless communications engineers. The coverage is comprehensive and includes summary chapters on the circuit theory needed to explain the theory and operation of phase-locked loops and the supporting mathematics necessary for analysis. These include concise discussions of Laplace transformations, z-Transformations, root locus, Bode analysis, partial fraction expansion, and others. The material develops systematically from analog through digital loops. Included is broad coverage of synchronization methods and techniques, modern digital interpolation techniques in modem design, modem acquisition and tracking, fading channel performances, as well as practical rules-of-thumb for modem designers to use in specifying loop bandwidths for good performances. The book provides numerous real world applications, and each chapter has problem sets that reinforce important concepts presented. "Phase-Locked Loops for Wireless Communications: Digital and Analog Implementations" features a complete collection of topics needed by both the wireless and traditional phase-locked loop specialist to design and analyze high performance circuits and software algorithms.

This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for writing the text was to present a complete tutorial of phase-locked loops with a consistent notation. As such, it can serve as a textbook in formal classroom instruction, or as a self-study guide for the practicing engineer. A former colleague, Kevin Kreitzer, had suggested that I write a text, with an emphasis on digital phase-locked loops. As modem designers, we were continually receiving requests from other engineers asking for a definitive reference on digital phase-locked loops. There are several good papers in the literature, but there was not a good textbook for either classroom or self-paced study. From my own experience in designing low­ phase noise synthesizers, I also knew that third-order analog loop design was omitted from most texts. With those requirements, the material in the text seemed to flow naturally. Chapter 1 is the early history of phase-locked loops. I believe that historical knowledge can provide insight to the development and progress of a field, and phase-locked loops are no exception. As discussed in Chapter 1, consumer electronics (color television) prompted a rapid growth in phase-locked loop theory and applications, much like the wireless communications growth today. xiv Preface Although all-analog phase-locked loops are becoming rare, the continuous­ time nature of analog loops allows a good introduction to phase-locked loop theory.

Praise for the previous edition: “A complete overview of the subject which does not intimidate the reader but rather spurns interest and understanding in the subject.”European Energy and Environmental Law Review “…(the book is) scholarly yet accessible and very readable; thoroughly recommended.”Law Institute JournalDescriptionThe law of the sea provides for the regulation, management and governance of the ocean spaces that cover over two-thirds of the Earth’s surface. This book provides a comprehensive assessment of the foundational principles of the law of the sea, a critical overview of the 1982 United Nations Convention on the Law of the Sea and an analysis of subsequent developments including many bilateral, regional, and global agreements that supplement the Convention.The third edition of this acclaimed text has been thoroughly revised and updated, and now incorporates a dedicated chapter on natural and artificial islands. All of the main areas of the law of the sea are addressed including the foundations and sources of the law, the nature and extent of the maritime zones, the delimitation of overlapping maritime boundaries, the place of archipelagic and other special states in the law of the sea, navigational rights and freedoms, military activities at sea, marine scientific research, and marine resource and conservation issues such as fisheries, marine environmental protection and dispute settlement.The book also takes stock of contemporary oceans governance issues not adequately addressed by the Convention. Overarching challenges facing the law of the sea are considered, including how new maritime security initiatives can be reconciled with traditional navigational rights and freedoms, the need for stronger legal and policy responses to protect the global ocean environment from climate change and ocean acidification, and work on a new agreement for the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction.

FOREST ECOLOGY Authoritative resource covering traditional plant ecology topics and contemporary components such as climate change, invasive species, ecosystem services, and more Forest Ecology provides comprehensive coverage of the field, focusing on traditional plant ecology topics of tree structure and growth, regeneration, effects of light and temperature on tree physiology, forest communities, succession, and diversity. The work also reviews abiotic factors of light, temperature, physiography (landforms and topography), soil, and disturbance (especially fire), and provides coverage of ecosystem-level topics including carbon storage and balance, nutrient cycling, and forest ecosystem productivity. The 5th edition of Forest Ecology retains the readability and accessibility of the previous editions and includes important additional topical material that has surfaced in the field. All topics are approached with a landscape ecosystem or geo-ecological view, which places biota (organisms and communities) in context as integral parts of whole ecosystems that also include air (atmosphere and climate), topography, soil, and water. As such, the book fills a niche utilized by no other forest ecology text on the market, helping students and researchers consider whole ecosystems at multiple scales. Sample topics covered in Forest Ecology include: Contemporary components of forest ecology, including climate change, invasive species, diversity, ecological forestry, landscape ecology, and ecosystem services.Characteristics of physiography important for forest ecosystems, including its effects on microclimate, disturbance, soil, and vegetation.Genetic diversity of woody plants and genecological differentiation of tree species, including the importance of hybridization, polyploidy, and epigenetics.Site quality estimation using tree height and ground flora, and multiple-factor approaches to forest site and ecosystem classification and mapping. Forest Ecology is a highly accessible text for students, but it also serves as an excellent reference for academics. In addition, practitioners of forest ecology can also harness the information within to gain better insight into the field for practical application of concepts.

This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com­ prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan­ ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
