TL;DR: In this article, the authors provide a complete picture of the Wideband CDMA (Code Division Multiple Access) air interface of the 3rd generation cellular systems - UMTS (Universal Mobile Telecommunications Systems).
Abstract: From the Publisher: WCDMA for UMTS provides a complete picture of the Wideband CDMA (Code Division Multiple Access) air interface of the 3rd generation cellular systems - UMTS (Universal Mobile Telecommunications Systems). WCDMA is designed for multimedia communications including high quality images and video, and access to services with high data rates. These capabilities will create new business opportunities for manufacturers, operators and for the providers of content and applications. * Explains the key parts of the WCDMA standard and provides guidelines for its efficient use * Presents network dimensioning and coverage and capacity planning of WCDMA * Introduces radio resource management algorithms in the WCDMA network * Examines the coverage and capacity of WCDMA up to 2Mbps using numerous simulation results * Introduces the TDD (Time Divisions Duplex) mode * Discusses the co-existence of TDD and FDD (Frequency Divisions Duplex) and highlights their main differences Now includes the main modifications made to the 3GPP standard up until the end of 2000 and features the following new material: * Reference terminal classes * Current status of UMTS licensing * Capacity upgrade paths and capacity per km2 * Inter-frequency handovers and inter-system handovers to GSM * Antenna diversity gain measurements in the WCDMA experimental system Written by leading experts in the field, this practical approach to the key features in WCDMA will have wide-ranging appeal to Research and Development Engineers, Practising Engineers, Cellular Operators, Technical Managers and Students on Telecommunications courses.

TL;DR: In this paper, the authors present an up-to-date overview of Long Term Evolution (LTE) in a systematic and clear manner, including an in-depth explanation of the background and standardization process before moving on to examine the system architecture evolution.
Abstract: From the editors of the highly successful WCDMA for UMTS, this new book gives a complete and up-to-date overview of Long Term Evolution (LTE) in a systematic and clear manner. It starts with an in-depth explanation of the background and standardization process before moving on to examine the system architecture evolution (SAE). The basics of air interface modulation choices are introduced and key subjects such as 3GPP LTE physical layer and protocol solutions are described. Mobility aspects and radio resource management together with radio and end-to-end performance are assessed. The voice solution and voice capacity in LTE are also illustrated. Finally, the main differences between LTE TDD and FDD modes are examined and HSPA evolution in 3GPP Releases 7 and 8 is described. LTE for UMTS is one of the first books to provide a comprehensive guide to the standards and technologies of LTE. Key features of the book include: Covers all the key aspects of LTE in a systematic manner Presents full description of 3GPP Release 8 LTE Examines the expected performance of LTE Written by experts actively involved in the 3GPP standards and product development.
