CDMA (Code Division Multiple Access) is one type of multiple access system used in radio communication. Other multiple access methods include TDMA, FDMA, etc. WCDMA (Wideband Code Division Multiple Access) is the main air interface used for third generation mobile communication systems – UMTS (Universal Mobile Telecommunication System) and is characterised by a wider band than CDMA.
WCDMA uses a wider radio band than CDMA, which was used for 2G systems, and has a high transfer rate and increased system capacity and communication quality by statistical multiplexing, etc. WCDMA efficiently utilises the radio spectrum to provide a maximum data rate of 2 Mbit/s. DOWNLOAD HERE
5. Springer Design and Performance of 3G Wireless Networks and Wireless LANs Sep 2005 eBook DDU Design and Performance of 3G Wireless Networks and Wireless LANs is for wireless communication system engineers, network engineers, professionals, and researchers. Network architectures of UMTS, CDMA2000 systems, and how major network elements within the 3G networks can be designed, are described. In addition, the authors describe how end-to-end performance for voice and data services can be determined. They also provide guidelines on how radio access networks and core networks can be engineered.
6. WCDMA FOR UMTS RADIO ACCESS FOR THIRD GENERATION MOBILE COMMUNICATIONS
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.

7. HSDPA HSUPA for UMTS High Speed Radio Access for Mobile Communications ebook-Spy
From the editors of the highly successful WCDMA for UMTS, this new book provides a comprehensive and up-to-date reference to High Speed Packet Access (HSPA) technologies for WCDMA. The editors cover both HSDPA and HSUPA, including an in-depth description and explanation of 3GPP standards, and expected performance based on simulations and first measurements. The text also discusses the impact of HSDPA and HSUPA on network dimensioning, covers applications and end-to-end performance in detail, and includes a section on radio frequency requirements and terminal design considerations.

A complete and practical guide to WCDMA/UMTS cellular network deployment.
After introducing the network architecture of such a system, the WCDMA (UMTS) Deployment Handbook defines the coverage and capacity concepts associated with the dimensioning and design phases. Progressing to a discussion of the main system parameters associated with network optimization and detailing optimization techniques for the main services supported by UMTS, and includes the specifics of indoor deployment and HSDPA networks evolution.

by Maciej Nawrocki, Hamid Aghvami
This book sets out to provide the theoretical foundations that will enable radio network planners to plan model and optimize radio networks using state-of-the-art findings from around the globe. It adopts a logical approach, beginning with the background to the present status of UMTS radio network technology, before devoting equal coverage to planning, modelling and optimization issues.
WCDMA (Wideband Code Division Multiple Access), an ITU standard derived from code division multiple access (CDMA) is officially known as IMT-2000 direct spread. WCDMA is a third generation mobile wireless technology offering much higher data speeds to mobile and portable wireless devices than commonly offered in today’s market. WCDMA is a relatively new technology and there is little information in the public domain about specific design issues.
Theory and Applications of OFDM and CDMA: Wideband Wireless Communications
Henrik Schulze, Christian Lueders
Theory and Applications of OFDM and CDMA is an ideal foundation textbook for those seeking a sound knowledge of this fast-developing field of wideband communications. The advanced transmission techniques of OFDM, applied in wireless LANs and in digital and video broadcasting, and CDMA, the foundation of 3G mobile communications, have been part of almost every communication system that has been designed in recent years, with both offering a high degree of flexibility in adjusting the system to the requirements of the application and to the impairments caused by the transmission channel.
12. The UMTS Network and Radio Access Technology.Air Interface Techniques for Future Mobile Systems
The UMTS Network and Radio Access Technology covers all the key aspects of UMTS and its implementation from both the engineering design and the operator and service providers’ point of view. It addresses the essential tasks involved in UMTS network deployment in new regions and within existing 2G networks. Presenting solutions for the integration and coexistence of 2G and 3G systems it discusses the seamless interoperability functions between GSM and UMTS.
UMTS (Universal Mobile Telecommunication System) is the third generation telecommunications system based on WCDMA. WCDMA (Wideband Code Division Multiple Access) is the radio interface for UMTS. WCDMA is characterised by use of a wider band than CDMA. It has additional advantages of high transfer rate, and increased system capacity and communication quality by statistical multiplexing, etc. WCDMA efficiently utilises the radio spectrum to provide a maximum data rate of 2 Mbit/s.

Mobile communications bring profound changes to our everyday lives.
The launch of 3rd generation mobile systems in 2001 in Japan and from 2002 throughout the rest of the world, will enable us to communicate at anytime and anywhere, by using a variety of services which have up to now only been available to fixed network users.
By the end of 2003, there are expected to be over one billion mobile telephones in use around the world, which surpasses the number of fixed telephone lines projected for that date.
