Wcdma: Requirements and Practical Design

WCDMA–Requirements and Practical Design discusses direct sequence CDMA, a well–established technology used in both second and third generation wireless standards. The authors provide practical information on the design, development and implementation of a WCDMA modem and protocol software.
Written in a methodical and highly accessible manner this book will appeal to professional communications engineers and software and hardware engineers, along with postgraduate students and academics.
The book:Addresses all aspects of the development of a WCDMA (UMTS) handset from the RF chain through the physical and protocol layers to the speech codec.Combines introductions to the 3GPP FDD WCDMA standard and practical engineering aspects of the development of user equipment allowing for a better understanding of the specifications.Discusses the physical layer, including the Rake receiver and turbo decoder, and the protocol layers giving the reader a comprehensive overview of the technology involved.Provides engineers with practical tips and advice from the engineers who develop WCDMA user equipment.
WCDMA–Requirements and Practical Design is an invaluable and practical reference, written by engineers developing third generation wireless technology. Its explanation of the specifications and potential problems with solutions will be extremely useful for those designing a 3G mobile wireless device.
