The definitive engineer's guide to designing and building software-based radios, this book introduces the key concepts of software radio design and covers every issue and technique engineers must understand to successfully utilize digital signal processing (DSP) in their radio systems and subsystems.

The definitive engineer's guide to designing and building software-based radios.

• The first systematic guide to software radio design and implementation
• Multirate DSP, RF front-ends, direct digital synthesis of modulated waveforms, A/D and D/A conversion, and more
• Enhancing performance through smart antennas and other adaptive array algorithms
• Techniques 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 design
• Direct digital synthesis of modulated waveforms
• A/D and D/A converters and conversion processes: key tradeoffs among resolution, sample rate, and dynamic range
• Enhancing performance through smart antennas and other adaptive array algorithms
• Practical techniques for choosing among DSP microprocessors, FPGAs, and ASICs
• A 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.
