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.
