Beschreibungen

<i>Ground Based Wireless Positioning</i> provides an in-depth treatment of non-GPS based wireless positioning techniques, with a balance between theory and engineering practice. The book presents the architecture, design and testing of a variety of wireless positioning systems based on the time-of-arrival, signal strength, and angle-of-arrival measurements. These techniques are essential for developing accurate wireless positioning systems which can operate reliably in both indoor and outdoor environments where the Global Positioning System (GPS) proves to be inadequate. The book covers a wide range of issues including radio propagation, parameter identification, statistical signal processing, optimization, and localization in large and multi-hop networks. A comprehensive study on the state-of-the-art techniques and methodologies in wireless positioning and tracking is provided, including anchor-based and anchor-free localisation in wireless sensor networks (WSN). The authors address real world issues such as multipath, non-line-of-sight (NLOS) propagation, accuracy limitations and measurement errors. <p>Presenting the latest advances in the field, <i>Ground Based Wireless Positioning</i> is one of the first books to cover non-GPS based technologies for wireless positioning. It serves as an indispensable reference for researchers and engineers specialising in the fields of localization and tracking, and wireless sensor networks.</p> <ul> <li>Provides a comprehensive treatment of methodologies and algorithms for positioning and tracking</li> <li>Includes practical issues and case studies in designing real wireless positioning systems</li> <li>Explains non-line-of-sight (NLOS) radio propagation and NLOS mitigation techniques</li> <li>Balances solid theory with engineering practice of non-GPS wireless systems</li> </ul>

From 2003 to 2005 he was employed as a Postdoctoral Fellow at the Centre for Wireless Communications, University of Oulu, Finland, researching on wireless positioning and communications theory. Since November 2005 he has served as a Research Scientist at CSIRO working on ad hoc wireless positioning systems, wireless sensor networks and reconfigurable radio. Kegen has published three book chapters, and over 40 refereed journal and conference papers. <p><b>Ian Sharp</b> is a Senior Consultant on wireless positioning systems. He has over 30 years of engineering experience in radio systems. His initial involvement in positioning technology was in aviation and later, in the 1980s, with the Interscan microwave landing system (MLS). In the later 1980s to the early 1990s, Ian was the R&D manager for the Quiktrak covert vehicle tracking system. This system is now commercially operating worldwide. From the mid 1990s to 2007 Ian worked at the CSIROmainly on developing experimental radio systems. Hewas the inventor and architect designer of CSIRO’s precision location system (PLS) for sports applications. The PLS has been successfully trialed in Australia and the USA. Ian holds a number of patents relating to positioning technology.</p> <p><b>Professor</b> <b>Y Jay Guo</b> is the Director of the Wireless Technologies Laboratory and Theme Leader of Broadband for Australia in the CSIRO ICT Centre, Australia. Prior to this appointment in August 2005, Jay held various senior positions in the European wireless industry managing the development of advanced technologies for the third-generation (3G) mobile communications systems. Jay has over 20 years of industrial and academic experience in antennas, signal processing and wireless networks. He has published three technical books and over 100 scientific papers in top-tier research journals and at international conferences. He holds 12 patents in wireless technologies. He is a Fellow of IET, Adjunct Professor at Macquarie University, Australia, and Guest Professor at the Chinese Academy of Science (CAS).</p>
