Software Radio : A Modern Approach to Radio Engineering
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. This is the first comprehensive educational resource for students who want to learn the latest techniques for building software radios for wireless systems and devices. It 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, including key interactions amongst analog and digital subsystems. Coverage includes: the central role of multirate DSP in software radio design; advanced digital processing techniques for constructing RF front-ends; direct digital synthesis of modulated waveforms; A/D and D/A converters and conversion processes; and smart antennas and adaptive array algorithms. The author also offers practical guidance for choosing among DSP microprocessors, FPGAs, and ASICs; as well as a systematic, object-oriented approach to programming software-based radios.

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.
