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.
