In order to cope with the tremendous explosion of thetelecommunications market, the field of wireless communications hasgreatly expanded in the past fifty years, especially in the domainsof microwave radio systems including line-of-sight, satellites, andtropospheric-scatter. Now, Microwave Engineering: Land & SpaceRadio- communications answers the growing worldwide demand for anauthoritative book on this important and emerging subject area.
In five succinct chapters, the book introduces students andpracticing engineers to the main propagation phenomena that areencountered and that must be considered in the design and planningfor any given system type and frequency of operation:
Electromagnetic wave propagation—An introduction to thefundamentaltheory of radiation and propagation of electromagneticwaves, polarization, antenna properties, free space attenuation,atmospheric refractivity, diffraction, reflection, multipath andscattering mechanisms, hydrometeor effects, and probabilitydistributions
Principles of digital communication systems—Modulationtechniques, signal processing, error probability, spectralcharacteristics, spectrum efficiency, thermal noise,intermodulation, jamming, and interference
Microwave line-of-sight systems—Path profile, flat fadingand frequency-selective fading, interferometric method for spaceand frequency diversity techniques, International Standards and ITURecommendations, optimization of the frequency-plan resource, linkbudget, quality, reliability, and availability
Microwave transhorizon systems—Design ofbeyond-the-horizon communication systems, properties of scatteringand diffraction modes, multipath statistical relations, long-termand short-term field strength variations, quality of service,optimization of antenna alignment, and experimental analysis ofvarious diversity and combining methods
Satellite communications—Design of satellitecommunications systems, orbital parameters, Earth-satellitegeometry, uplink and downlink budgets for both space and Earthsegments, and total system noise temperature
Microwave Engineering: Land & Space Radiocommunications issuitable for engineers involved in wireless telecommunications, aswell as for students and members of various seminars andworkshops.

From outdoors to indoors
From ancient to future applications
From techniques to technologies . . .
The field of radionavigation signals and systems has seensignificant growth in recent years. Satellite systems are veryefficient, but owing to their limited exposure and/or availabilityin some environments, they do not cover the whole spectrum ofapplications. Thus, many other positioning techniques are beingdeveloped.
Now, Global Positioning presents an overview of the strengthsand weaknesses of various systems with a specific emphasis on thosethat are satellite-based. Beginning with a description of theevolution of positioning systems, the book provides detailedcoverage of the three main Global Navigation Satellite System(GNSS) constellations, discusses how to cope with indoorpositioning, defines development activities and commercialpositioning, and proposes a vision for the future of the field.
Special features of the book include:
Exercises to test and challenge the reader's understanding
Direct comparison between constellations and other positioningsystems
Mathematical content kept to a minimum in order to maximizeaccessibility and readability
Descriptions of European and U.S. discussions for Galileo
Historical aspects and links between the distant past andcurrent systems
Footnotes that provide hints and comments to the reader
At a time when the positioning domain is experiencing suchimmense transformation, it is vital to have a solid understandingof the fundamental principles, current tech-nologies, and futureimprovements that will help estimate the performance andlimita-tions of existing systems. Global Positioning fills animportant need for professionals and students in a variety offields who want a complete and authoritative overview of globalpositioning techniques.
