Radiowave Propagation and Smart Antennas for Wireless Communications (The Kluwer International Series in Engineering and Computer Science Volume 599) (The ... Series in Engineering and Computer Science)

Useful as a text as well as a reference, this is one of the first books of its kind to combine basic and advanced topics of radiowave propagation and smart antennas into a single volume. The book is interdisciplinary in nature and contains material drawn from the electromagnetics and communications areas. Physical phenomena leading to the modeling and prediction of path loss, and characterizing the small-scale and medium-scale fluctuations of the received signal, are treated in detail. Several new path loss models are included. Both narrowband and wideband radio channel characterizations are discussed. Statistical descriptions of geometrically based single bounce scattering models that are useful in developing spatial channel models for smart arrays are presented. Principles of diversity and smart antennas for reducing fading and co-channel interference are presented. Performance evaluation of these arrays in the presence of fading and shadowing is treated. Both TDMA and CMDA systems are considered. Effects of element mutual coupling and correlation in limiting the system performance are elaborated. Finally, principles of multiple-input multiple-output communication systems that are increasingly becoming attractive owing to their enormous bit rate capabilities are covered. Several practical examples are worked out throughout the text. Additional problems that help the reader assimilate the material and advance to higher-level topics are included at the end of each chapter. Radiowave Propagation and Smart Antennas for Wireless Communications has been written for use in a graduate course on communications and represents a comprehensive reference for research scientists and practitioners working in fields related to the topic. This book emerged from teaching a graduate level course in propagation and smart antennas at the Naval Postgraduate School. In its present form, it is suitable not only as a graduate level text, but also as a reference book for industry and research use. The area of radiowave propagation and smart antennas is highly interdisciplinary, extracting material from electromagn- ics, communications, and signal processing. This book is useful to workers in electromagnetics who would like to supplement their background with relevant communicational aspects and to workers in communications who would like to supplement their background with relevant electromagnetic aspects. Anyone with a basic understanding of probability, wave propagation, digital com- nications, and elementary signal processing should be able to appreciate the contents of the book. The book consists of nine chapters with several worked out examples d- persed throughout. Chapter 1 covers the basics of cellular communications. Chapter 2 covers the basic principles of electromagnetic wave propagation relevant to path loss predictions in wireless communications. Students with little prior background in electromagnetics should find the first few sections of Chapter 2 self-sufficient. Empirical path loss models that are used in system design are treated in Chapter 3. The chapter includes the traditional models as well as some of the newer models. Chapter 4 has a thorough discussion on the causes and characterization of small scale fading. The topic of spatial c- relation that is very important for antenna arrays is discussed there in detail.
