A comprehensive reference giving a thorough explanation of propagation mechanisms, channel characteristics results, measurement approaches and the modelling of channels Thoroughly covering channel characteristics and parameters, this book provides the knowledge needed to design various wireless systems, such as cellular communication systems, RFID and ad hoc wireless communication systems. It gives a detailed introduction to aspects of channels before presenting the novel estimation and modelling techniques which can be used to achieve accurate models. To systematically guide readers through the topic, the book is organised in three distinct parts. The first part covers the fundamentals of the characterization of propagation channels, including the conventional single-input single-output (SISO) propagation channel characterization as well as its extension to multiple-input multiple-output (MIMO) cases. Part two focuses on channel measurements and channel data post-processing. Wideband channel measurements are introduced, including the equipment, technology and advantages and disadvantages of different data acquisition schemes. The channel parameter estimation methods are then presented, which include conventional spectral-based estimation, the specular-path-model based high-resolution method, and the newly derived power spectrum estimation methods. Measurement results are used to compare the performance of the different estimation methods. The third part gives a complete introduction to different modelling approaches. Among them, both scattering theoretical channel modelling and measurement-based channel modelling approaches are detailed. This part also approaches how to utilize these two modelling approaches to investigate wireless channels for conventional cellular systems and some new emerging communication systems. This three-part approach means the book caters for the requirements of the audiences at different levels, including readers needing introductory knowledge, engineers who are looking for more advanced understanding, and expert researchers in wireless system design as a reference. Presents technical explanations, illustrated with examples of the theory in practice Discusses results applied to 4G communication systems and other emerging communication systems, such as relay, CoMP, and vehicle-to-vehicle rapid time-variant channels Can be used as comprehensive tutorial for students or a complete reference for engineers in industry Includes selected illustrations in color Program downloads available for readers Companion website with program downloads for readers and presentation slides and solution manual for instructors Essential reading for Graduate students and researchers interested in the characteristics of propagation channel, or who work in areas related to physical layer architectures, air interfaces, navigation, and wireless sensing

A valuable addition to the Wiley Series in Microwave and OpticalEngineering Today's modern wireless mobile communications depend on adaptive"smart" antennas to provide maximum range and clarity. With therecent explosive growth of wireless applications, smart antennatechnology has achieved widespread commercial and militaryapplications. The only book available on the topic of adaptive antennas usingdigital technology, this text reflects the latest developments insmart antenna technology and offers timely information onfundamentals, as well as new adaptive techniques developed by theauthors. Coupling electromagnetic aspects of antenna design withsignal processing techniques designed to promote accurate andefficient information exchange, the text presents variousmechanisms for characterizing signal-path loss associated withsignal propagation, particularly for mobile wireless communicationssystems based on such techniques as joint space-frequency adaptiveprocessing. In clear, accessible language, the authors: * explain the difference between adaptive antennas and adaptivesignal processing * Illustrate the procedures for adaptive processing using directiveelements in a conformal array * clarify multistage analysis procedure which combineselectromagnetic analysis with signal processing * present a survey of the various models for characterizing radiowave propagation in urban and rural environments * describe a method wherein it is possible to identify andeliminate multipath without spatial diversity * optimize the location of base stations in a complexenvironment The text is an excellent resource for researchers and engineersworking in electromagnetics and signal processing who deal withperformance improvement of adaptive techniques, as well as thosewho are concerned with the characterization of propagation channelsand applications of airborne phased arrays.
