A comprehensive reference giving a thorough explanation ofpropagation mechanisms, channel characteristics results,measurement approaches and the modelling of channelsThoroughly covering channel characteristics and parameters, thisbook provides the knowledge needed to design various wirelesssystems, such as cellular communication systems, RFID and ad hocwireless communication systems. It gives a detailed introduction toaspects of channels before presenting the novel estimation andmodelling techniques which can be used to achieve accuratemodels.To systematically guide readers through the topic, the book isorganised in three distinct parts. The first part covers thefundamentals of the characterization of propagation channels,including the conventional single-input single-output (SISO)propagation channel characterization as well as its extension tomultiple-input multiple-output (MIMO) cases. Part two focuses onchannel measurements and channel data post-processing. Widebandchannel measurements are introduced, including the equipment,technology and advantages and disadvantages of different dataacquisition schemes. The channel parameter estimation methods arethen presented, which include conventional spectral-basedestimation, 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 thedifferent estimation methods. The third part gives a completeintroduction to different modelling approaches. Among them, bothscattering theoretical channel modelling and measurement-basedchannel modelling approaches are detailed. This part alsoapproaches how to utilize these two modelling approaches toinvestigate wireless channels for conventional cellular systems andsome new emerging communication systems. This three-partapproach means the book caters for the requirements of theaudiences at different levels, including readers needingintroductory knowledge, engineers who are looking for more advancedunderstanding, and expert researchers in wireless system design asa reference.* Presents technical explanations, illustrated with examples ofthe theory in practice* Discusses results applied to 4G communication systems and otheremerging communication systems, such as relay, CoMP, andvehicle-to-vehicle rapid time-variant channels* Can be used as comprehensive tutorial for students or acomplete reference for engineers in industry* Includes selected illustrations in color* Program downloads available for readers* Companion website with program downloads for readers andpresentation slides and solution manual for instructorsEssential reading for Graduate students and researchersinterested in the characteristics of propagation channel, orwho work in areas related to physical layer architectures, airinterfaces, navigation, and wireless sensing
