Available in PDF, EPUB and Kindle. Book excerpt: After a brief description of the significance of the radio refractive index and its variation in the lower troposphere, a catalog of fading mechanisms is presented. Attention is directed to the supporting refractive index structure, the characteristics of the fading signal, and the available remedies. The phenomena of multipath fading are described, and the theoretical amplitude distributions are presented. Diversity reception (frequency or space) is outlined for reducing the fading due to multipath. Specific expressions are given for determining the frequency or space separations.Successful remedies for microwave fading that are keyed to specific fading mechanisms also constitute a means of measuring the characteristics of the prevailing meteorological conditions. Specific expressions are given to accomplish this for the multipath and diffraction fading mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: After a brief description of the significance of the radio refractive index and its variation in the atmosphere, a brief catalogue of fading mechanisms is presented. Attention is directed to the variety of fading mechanisms that are pertinent for the propagation of radio waves when one or both terminals are airborne. The general characteristics of those fading mechanisms are presented and the techniques available for the reduction of fading are described. The phenomenon of multipath fading is described. The distributions for multipath propagation are discussed and presented. The device of diversity reception (frequency or space) is outlined for reducing the fading due to multipath. The phenomenon of diffraction fading is described both for diffraction by the earth's surface and by the atmospheric layers. The resulting radio holes are then specified in terms of the geometry and the pertinent refractivity gradients. The avoidance of radio holes for one or more airborne terminals is discussed.

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.
