Written by leading authority Ramjee Prasad, this timely new work offers a complete understanding of OFDM technology and applications in wireless communications systems, placing emphasis on wireless LANs and PANs. OFDM is a key technology for beyond 3G communications, promising robust, high capacity, high speed wireless broadband multimedia networks. In this practical resource, established and new technologies are explained clearly and comprehensively, from OFDM basics to a detailed account of a new technique, hybrid OFDM CDMA slow frequency hopping. The book offers an in-depth treatment of the underlying technologies and applications of PANs and describes and evaluates a practical OFDM system concept. Invaluable for wireless engineers and researchers, this cutting edge new book is a must-have for anyone who needs to understand this critical technology and its implementation in WLANs and WPANs.

A cost-effective alternative to classroom instruction, this unique UMTS system design course helps you quickly master the skills you need for your work in the field. Available as CD-ROM series, the course is divided in to three convenient three-hour segments (one CD per segment) Part 1: Access Technology and Air Interface helps you gain a thorough understanding of the UMTS architecture.. You explore all aspects of CDMA and WCDMA transmission technologies and learn the data and signaling processes on the UMTS air interface. Part 2: The Protocol Stack and Lower Layer Processing Details covers critical physical-layer procedures, such as power control operation and the cell search procedure. It includes an indepth presentation of the various layers of the UMTS protocol stack with a clear focus on the UTRAN, and detailed descriptions of important procedures such as soft and softer handover. Part 3: Higher Layer Procedures and Selected Scenarios examines UMTS higher layer procedures within the UTRAN and the mobile station. Key topics include session management, call control, mobility management, QoS, security and message flow.
