Available in PDF, EPUB and Kindle. Book excerpt: A theoretical-experimental study of absolute diffraction at microwave frequencies has been conducted. The filed strength in the geometric shadow zone can be predicted from classical (Fresnel-Kirchhoff) diffraction theory when the obstacle approximates the idealized knife edge. However, the modest amount of empirical knowledge available precludes an engineering evaluation of the obstacle-diffraction propagation mechanism from the viewpoint of microwave communications. This study was undertaken in order to describe more fully the characteristics of diffraction propagation, as well as to add to the body of experimental data. While the main concern was the total nature of the propagation, emphasis was given those factors which may affect the successful transmission of information. Conventional measurements of signal level and its variation in time were made. A unique aspect of the experiment was the use of frequency-swept transmission, allowing the direct observation of the propagation frequency response. Polarization and spatial dependence were also examined. The repeater model of diffraction, used implicitly in the literature, was derived and tested explicitly. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The first book to cover all engineering aspects of microwave communication path design for the digital age Fixed point-to-point microwave systems provide moderate-capacity digital transmission between well-defined locations. Most popular in situations where fiber optics or satellite communication is impractical, it is commonly used for cellular or PCS site interconnectivity where digital connectivity is needed but not economically available from other sources, and in private networks where reliability is most important. Until now, no book has adequately treated all engineering aspects of microwave communications in the digital age. This important new work provides readers with the depth of knowledge necessary for all the system engineering details associated with fixed point-to-point microwave radio path design: the why, what, and how of microwave transmission; design objectives; engineering methodologies; and design philosophy (in the bid, design, and acceptance phase of the project). Written in an easily accessible format, Digital Microwave Communication features an appendix of specialized engineering details and formulas, and offers up chapter coverage of: A Brief History of Microwave Radio Microwave Radio Overview System Components Hypothetical Reference Circuits Multipath Fading Rain Fading Reflections and Obstructions Network Reliability Calculations Regulation of Microwave Radio Networks Radio Network Performance Objectives Designing and Operating Microwave Systems Antennas Radio Diversity Ducting and Obstruction Fading Digital Receiver Interference Path Performance Calculations Digital Microwave Communication: Engineering Point-to-Point Microwave Systems will be of great interest to engineers and managers who specify, design, or evaluate fixed point-to-point microwave systems associated with communications systems and equipment manufacturers, independent and university research organizations, government agencies, telecommunications services, and other users.

Download or read book Wireless Communication Systems written by Ke-Lin Du and published by Cambridge University Press. This book was released on 2010-04-15 with total page 1020 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practically-oriented, all-inclusive guide covers all the major enabling techniques for current and next-generation cellular communications and wireless networking systems. Technologies covered include CDMA, OFDM, UWB, turbo and LDPC coding, smart antennas, wireless ad hoc and sensor networks, MIMO, and cognitive radios, providing readers with everything they need to master wireless systems design in a single volume. Uniquely, a detailed introduction to the properties, design, and selection of RF subsystems and antennas is provided, giving readers a clear overview of the whole wireless system. It is also the first textbook to include a complete introduction to speech coders and video coders used in wireless systems. Richly illustrated with over 400 figures, and with a unique emphasis on practical and state-of-the-art techniques in system design, rather than on the mathematical foundations, this book is ideal for graduate students and researchers in wireless communications, as well as for wireless and telecom engineers.
