THOROUGHLY REVISED AND UPDATED, THIS SECOND EDITION OFFERS A FUNDAMENTAL AND COMPREHENSIVE TREATMENT OF HOW MOBILE SYSTEMS OPERATE IN A VARIETY OF SCENARIOS. THIS UNRIVALLED APPROACH CONCENTRATES ON THE PROPERTIES OF THE RADIO CHANNEL, A VITAL AND CENTRAL FEATURE THAT PLACES FUNDAMENTAL LIMITATIONS ON THE PERFORMANCE OF RADIO SYSTEMS. BRINGING THE READER COMPLETELY UP–TO–DATE, THIS BOOK: * FEATURES TWO NEW CHAPTERS: 'MULTIPATH MITIGATION TECHNIQUES' AND 'RADIO SYSTEM PLANNING' * SURVEYS VARIOUS ALTERNATIVE METHODS OF PREDICTING THE MEAN SIGNAL STRENGTH AND ITS VARIABILITY, AND DISCUSSES THEIR APPLICATIONS * INTRODUCES RAY–TRACING METHODS IN CONNECTION WITH INDOOR PROPAGATION * DISCUSSES MULTIPATH AND ITS EFFECTS ON NARROWBAND AND WIDEBAND SYSTEMS * DESCRIBES CHANNEL SOUNDERS AND REVIEWS METHODS OF HARDWARE AND SOFTWARE SIMULATION * EXAMINES MAN–MADE NOISE AND INTERFERENCE AND DISCUSSES THE RESULTING PERFORMANCE DEGRADATION BY EQUIPPING THE READER WITH A THOROUGH UNDERSTANDING OF THE PHYSICAL PROCESSES THAT UNDERLIE THE PROPAGATION OF RADIO WAVES, THIS SYSTEMATIC APPROACH WILL PROVE TO BE AN AUTHORITATIVE AND ATTRACTIVE TEXT FOR RESEARCHERS, SYSTEMS DESIGNERS, UNIVERSITY ACADEMICS AND POSTGRADUATE STUDENTS.

Reseña del editor:
Mobile systems operate in a variety of different scenarios. These include remote rural areas, where the terrain is irregular, dense urban areas where buildings dominate, and even inside those buildings. Equipment can either be carried by pedestrians or be in a high-speed vehicle or train. Various alternative methods of predicting the mean signal strength and its variability are surveyed and their applicability to a particular situation is discussed. Ray-tracing methods are introduced in connection with indoor propagation. Multipath, probably the single most destructive influence on mobile systems is extensively characterised, and its effects on narrowband and wideband systems are discussed. Channel sounders, used to obtain practical measurements, are described and methods of hardware and software simulation are reviewed. The emphasis throughout is on a physical understanding of the phenomena which influence radio signals in mobile radio systems.
