Wideband TDD: WCDMA for the Unpaired Spectrum


Wideband TDD: WCDMA for the Unpaired Spectrum
Wiley May 28, 2004 ISBN: 0470861045 286 pages PDF 5 Mb
3rd generation radio systems will be increasingly developed, deployed and operated in the years to come. TDD is one of two main approaches to implementing these 3G systems, so that there will be an increasing need for the engineering community to learn quickly and comprehensively about the TDD technology. As 3G systems become popular, the topics will no doubt be introduced to academic curricula and will also provide a basis for future research.
This book provides comprehensive coverage of TDD. It is essentially a Radio Access Network technology and the book embraces the structure of the radio interface as well as the user equipment and network equipment. In addition, Wideband TDD also covers the connection of the TDD Radio Access Network to the 3G Core Network and public switched networks (PSTN) as well as public and private packet networks (Internet and Intranet). Services, applications and performance are also addressed. Finally, TDD is compared with other radio access technologies, namely FDD, TD-SCDMA and WLAN. TD-SCDMA is the Narrowband version of TDD in 3G, and WLAN standards address wireless computer communications.
Although there are a number of books published on 3G and UMTS, most of the focus of these books has been on FDD component of 3G.Wideband TDD:
* Describes all aspects of TDD in a single comprehensive manner
* Addresses TDD technology, TDD systems and the TDD market place
* Discusses deployment scenarios and Radio Resource Management for TDD
* Provides a comparison of TDD with other radio access technologies, namely FDD, TD-SCDMA and wireless LANs
This will prove an essential addition to the bookshelf of professional communication and software engineers, development engineers, technical marketing professionals, researchers in industry, wireless equipment vendors such as Siemens, Nokia and InterDigital, operators and service providers.It will also provide a comprehensive overview of TDD for postgraduates who are taking advanced courses in Mobile Wireless communications.
From the Back Cover
The 3rd generation mobile wireless technology standardized by 3GPP has two main components, namely FDD (Frequency Division Duplex) and TDD (Time Division Duplex). While both of these employ WCDMA, the former uses a pair of frequency bands and the latter uses a single unpaired frequency band. Within TDD, two versions have been standardized, namely the Wideband TDD (also referred to as High Chip Rate TDD) and Narrowband TDD (also referred to as Low Chip Rate TDD or TD-SCDMA). Wideband TDD: WCDMA for the Unpaired Spectrum focuses on the Wideband TDD version. It brings together in one place the vast TDD related information, scattered amongst the numerous 3GPP Technical Specifications and Reports. The book also presents significant amount of valuable information related to Receiver, Radio Resource Management and Network implementation technologies (not found in Standards).
The book offers:
* A comprehensive overview of WTDD Technology for the engineering, research and student communities.
* A background to the fundamentals of WCDMA & Time Division Duplexing.
* Detailed account of the WTDD Radio Interface, including Protocols and Procedures
* Presentation of Receiver Signal Processing and Radio Resource Management techniques
* Exposition of various Deployment Scenarios and Techniques
* A comparison of TDD and other radio access technologies, namely TD-SCDMA and WLAN. Written in an accessible manner this book will be highly popular with engineering and technical marketing professionals from network operators, mobile equipment and component manufacturers, as well as industry regulators and academia. Postgraduates who are taking advanced courses in Mobile Wireless communications will also find Wideband TDD: WCDMA for the Unpaired Spectrum invaluable.

WCDMA for UMTS: Radio Access for Third Generation Mobile Communications

WCDMA for UMTS: Radio Access for Third Generation Mobile Communications
Wiley September 15, 2004 ISBN: 0470870966 PDF 478 pages 7 MB

As wireless communications technologies evolve, Wideband Code Division Multiple Access (WCDMA) seems a strong candidate for providing multimedia to the handset, as well as Universal Mobile Telecommunications Services (UMTS)--which is to say common wireless communications standards over most of the world. WCDMA for UMTS sets out to decipher the standards documents of the Third Generation Partnership Project (3GPP). Specifically, this book deals with the 3GPP documents on Frequency Division Duplex (FDD) and Time Division Duplex (TDD) for Universal Terrestrial Radio Access (UTRA). This book should prove valuable to readers who plan to implement WCDMA in hardware designs or service offerings.
A series of engineering problems make up the backbone of the book, and each part of the deployment process is explained via text and calculations. For example, in the discussion on planning a radio network for WCDMA service provision, the book explains precisely how to take into account requirements (for quality of service, user capacity, and coverage) and conditions (such as terrain). Readers get formulas into which they can plug relative traffic predictions for voice, real-time data, non-real-time data, and overhead. There's also an explanation of how to interpret the formula output for deploying antennae. This is a serious engineering handbook for those who are involved in deploying WCDMA.

WCDMA: Requirements and Practical Design


During 2001 we surveyed the literature for books describing developing a Wideband Code Division Multiple Access (WCDMA) modem. We knew the book by Young [1] which is a well written textbook with an emphasis on RF, from an engineer with many years industrial hands-on experience. Another good book, with an emphasis on digital signal processing, is by Frerking [2], who gives enough theoretical background to solve practical problems in modem design. Both books cover the technology and engineering aspects well for frequency and time division duplex systems, but not code division multiple access modems.

Advanced FPGA Design: Architecture, Implementation, and Optimization


This book provides the advanced issues of FPGA design as the underlying theme of the work. In practice, an engineer typically needs to be mentored for several years before these principles are appropriately utilized. The topics that will be discussed in this book are essential to designing FPGA's beyond moderate complexity. The goal of the book is to present practical design techniques that are otherwise only available through mentorship and real-world experience.
From the Back Cover
A practical FPGA reference that's like an on-call mentor for engineers and computer scientists
Addressing advanced issues of FPGA (Field-Programmable Gate Array) design and implementation, Advanced FPGA Design: Architecture, Implementation, and Optimization accelerates the learning process for engineers and computer scientists. With an emphasis on real-world design and a logical, practical approach, it walks readers through specific challenges and significantly reduces the learning curve. Designed to enhance and supplement hands-on experience, this real-world reference includes:
* Waveform diagrams and circuit diagrams illustrating each topic

* Examples that illustrate typical problems in Verilog

* Case studies that demonstrate real-world applications

* Chapter-end summaries that reiterate key points
Ideal for engineers and computer scientists who want to take their FPGA skills to the next level and for use as a hands-on reference, this is also an excellent textbook for senior or graduate-level students in electrical engineering or computer science.
Summary: Great FPGA Reference Book

Rating: 5
This is a great reference book for any level FPGA designer. This book skips past the basics unlike most books on FPGA design and jumps right into advanced topics that practical FPGA designers need to be aware of.
Plenty of discussion on the trade offs that must be faced in FPGA design based on you desired optimization target (speed, size, & power) and discussion of methods to achieve that goal. Lots of practical example code is used to illustrate each topic.
Discussion of simulation techniques and coverage which is becoming a key factor in verifying HDL based designs.
This book contains several topics that I have been waiting to see discussed well in a textbook including floorplanning and the pitfall of using asynchronous resets.
Besides HDL design techniques, the author discusses the PCB level design methodologies that must be used when designing an FPGA into a system. This disscussion is a great complement to this already fine book.
Summary: The real design warriors guide

Rating: 5
Finally! A book that actually talks about advanced design techniques instead of giving a historical overview of FPGA design.
I have to admit that I didn't read this book cover to cover. Rather, I use it for reference as needed. It's starting to get that same tabbed look that my other reference books have.
Summary: Excellent coverage of FPGA design

Rating: 5
I felt the author was well versed in real-world FPGA design. This book doesn't discuss any of the basics, but does an excellent job in explaining topics such as architecting for speed, synthesis, and place and route optimization, etc. This is the most useful FPGA book that I've read.
Summary: Very pleased with book

Rating: 5
I found the book to be quite helpful. I liked the presentation of practical examples. I would recommend this book any serious FPGA designer.
Summary: From the author

Rating: 5
For your convenience, I am publishing errata on my website: [...]
Background on the book:
After having been exposed to a wide variety of designs in a wide range of industries, I began developing my own arsenal of techniques and heuristics from the combined knowledge of these experiences. When mentoring new FPGA design engineers, I draw my suggestions and recommendations from this experience. Up until now, many of these recommendations have referenced specific white papers and application notes (appnotes) that discuss specific practical aspects of FPGA design. The purpose of this book is to condense years of experience spread across numerous companies and teams of engineers, as well as much of the wisdom gathered from technology-specific white papers and appnotes, into a single book that can be used to refine a designer's knowledge and aid in becoming an advanced FPGA designer.
There are a number of books on FPGA design, but few of these truly address advanced real-world topics in detail. This book attempts to cut out the fat of unnecessary theory, speculation on future technologies, and the details of outdated technologies. It is written in a terse, concise format that addresses the various topics without wasting the reader's time. Many sections in this book assume that certain fundamentals are understood, and for the sake of brevity, background information and/or theoretical frameworks are not always covered in detail. Instead, this book covers in-depth topics that have been encountered in real-world designs. In some ways, this book replaces a limited amount of industry experience and access to an experienced mentor and will hopefully prevent the reader from learning a few things the hard way. It is the advanced, practical approach that makes this book unique.
One thing to note about this book is that it will not flow from cover to cover like a novel. For a set of advanced topics that are not intrinsically tied to one another, this type of flow is impossible without blatantly filling it with fluff. Instead, to organize this book, I have ordered the chapters in such a way that they follow a typical design flow. The first chapters discuss architecture, then simulation, then synthesis, then floorplanning, and so on. This is illustrated in the Flowchart of Contents provided at the beginning of the book. To provide accessibility for future reference, the chapters are listed side-by-side with the relevant block in the flow diagram. The remaining chapters in this book are heavy with examples. For brevity, I have selected Verilog as the default HDL (Hardware Description Language). Xilinx as the default FPGA vendor, and Synplicity as the default synthesis and floorplanning tool. Most of the topics covered in this book can easily be mapped to VHDL, Altera, Mentor Graphics, and so forth, but to include all of these for completeness would only serve to cloud the important points. Even if the reader of this book uses these other technologies, this book will still deliver its value. If you have any feedback, good or bad, feel free to email me at the address listed in the preface.

Optical WDM Networks


Optical WDM Networks

Publisher: Springer Pages: 956 2006-01-13 ISBN 0387290559 PDF 44 MB


Research and development on optical wavelength-division multiplexing (WDM) networks have matured considerably. While optics and electronics should be used appropriately for transmission and switching hardware, note that "intelligence'' in any network comes from "software,'' for network control, management, signaling, traffic engineering, network planning, etc.The role of software in creating powerful network architectures for optical WDM networks is emphasized.

Optical WDM Networks is a textbook for graduate level courses. Its focus is on the networking aspects of optical networking, but it also includes coverage of physical layers in optical networks. The author introduces WDM and its enabling technologies and discusses WDM local, access, metro, and long-haul network architectures. Each chapter is self-contained, has problems at the end of each chapter, and the material is organized for self study as well as classroom use. The material is the most recent and timely in capturing the state-of-the-art in the fast-moving field of optical WDM networking.
