Software Radios: A Modern Approach to Radio Engineering by Jeffrey Hugh Reed,

Software Radios: A Modern Approach to Radio Engineering by Jeffrey Hugh Reed,
The definitive engineer's guide to designing and building software-based radios.The first systematic guide to software radio design and implementationMultirate DSP, RF front-ends, direct digital synthesis of modulated waveforms, A/D and D/A conversion, and moreEnhancing performance through smart antennas and other adaptive array algorithmsTechniques for building more flexible, extensible software Radios, once implemented purely in hardware, are increasingly built using programmable digital signal processing (DSP) devices that enhance device flexibility, simplify manufacture, and reduce costs. However, many engineers are unfamiliar with the latest techniques for building software radios for wireless systems and devices. This book fills the gap, introduces the key concepts of software radio design, and covers every issue and technique engineers must understand to successfully utilize DSP in their radio systems and subsystems. Coverage includes: Central role of multirate DSP in software radio design Constructing RF front-ends: utilizing digital processing to overcome key problems in RF designDirect digital synthesis of modulated waveformsA/D and D/A converters and conversion processes: key tradeoffs among resolution, sample rate, and dynamic rangeEnhancing performance through smart antennas and other adaptive array algorithmsPractical techniques for choosing among DSP microprocessors, FPGAs, and ASICsA systematic, object-oriented approach to creating flexible software The book concludes with case studies drawn from the advanced work of the SDR Forum, the leading consortium of companies, universities, and research organizations promoting software radio development.

Interferometry and Synthesis in Radio Astronomy by A. Richard Thompson,
Interferometry and Synthesis in Radio Astronomy by A. Richard Thompson,
Comprehensive, authoritative coverage of interferometric techniques for radio astronomy In this Second Edition of Interferometry and Synthesis in Radio Astronomy, three leading figures in the development of large imaging arrays, including very-long-baseline interferometry (VLBI), describe and explain the technology that provides images of the universe with an angular resolution as fine as 1/20,000 of an arcsecond. This comprehensive volume begins with a historical review followed by detailed coverage of the theory of interferometry and synthesis imaging, analysis of interferometer response, geometrical relationships, polarimetry, antennas, and arrays. Discussion of the receiving system continues with analysis of the response to signals and noise, analog design requirements, and digital signal processing. The authors detail special requirements of VLBI including atomic frequency standards, broadband recording systems, and antennas in orbit.Further major topics include: Calibration of data and synthesis of imagesImage enhancement using nonlinear algorithmsTechniques for astrometry and geodesyPropagation in the neutral atmosphere and ionized mediaRadio interferenceRelated techniques: intensity interferometry, moon occultations, antenna holography, and optical interferometry Interferometry and Synthesis in Radio Astronomy, Second Edition is comprehensive in that it provides an excellent overview of most radio astronomical instrumentation and techniques.

Antenna (radio) - Most simply, an antenna or aerial is an electronic component designed to transmit or receive radio waves. The words "antenna" and "aerial" are used throughout this article with precisely the same meaning.

Beverage antenna - The Beverage Antenna is a type of long-wire antenna designed for amateur radio usage, shortwave listening, and longwave radio applications. First used in the 1920s and named for its inventor Harold Beverage, it is not a beverage can or beer can antenna.

Parabolic antenna - The Parabolic antenna is a high-gain, reflector antenna used for radio, television and data communications, and also for radiolocation (RADAR), on the UHF and SHF frequencies. The relatively short wavelength of electromagnetic (radio) energy at these frequencies allows reasonably sized reflectors to exhibit the very desirable highly directional response for both receiving and transmitting.

Receiver (radio) - In radio terminology, a receiver is an electronic device that receives a radio signal from an antenna and decodes the signal for use as sound, pictures, navigational-position information, etc. Radio and radio receiver are often used specifically for receivers whose output consists only of sound, although other types of receivers, such as television receivers, are technically radio receivers as well.
