An engineer’s guide to systems engineering of software-radio architectures

As a crucial element of wireless technology, software radio is fast becoming a hot topic in the telecommunications field. This new book provides complete, up-to-date coverage of software radio architecture, discussing in detail functions, components, design procedures for complex radio systems, and large-scale software engineering methods such as UML and CORBA. The author bridges the inter-disciplinary gap in the field, covering what software engineers need to know about how radio "waveforms" are defined in software. Plus, he provides tutorial material on how the Unified Modeling Language–UML–is used for specifying radio architecture. The architecture tradeoffs–how to deliver predictably robust performance without unnecessarily expensive hardware, economic principles, cost considerations, and marketplace trends–are also addressed. Coverage includes:

• Market-oriented technology trends on how software radio fits in with the larger telecommunications marketplace
• Complexity drivers and their influence on hardware and software components
• System integration, emphasizing the management of processing capacity available on heterogeneous ASIC, FPGA, and DSP hardware
• Subsystem material and the unique requirements that software radio brings to the hardware and software segments–antennas, RF conversion, ADC/DAC, pooled DSP, real-time operating systems, CORBA middleware, and radio software objects
• Relevant areas of systems engineering, including design tools, cost-benefit analysis, and an extended case study, "Mobile Infrastructure for Joint Military-Civilian Disaster Relief"
• Hundreds of graphs, case studies, and Internet access to software design tools (email: [email protected])

An exciting new technology, described by the one who invented it

This is the first book dedicated to cognitive radio, a promising new technology that is poised to revolutionize the telecommunications industry with increased wireless flexibility. Cognitive radio technology integrates computational intelligence into software-defined radio for embedded intelligent agents that adapt to RF environments and user needs. Using this technology, users can more fully exploit the radio spectrum and services available from wireless connectivity. For example, an attempt to send a 10MB e-mail in a zone where carrier charges are high might cause a cognitive radio to alert its user and suggest waiting until getting to the office to use the LAN instead. Cognitive Radio Architecture examines an "ideal cognitive radio" that features autonomous machine learning, computer vision, and spoken or written language perception.

The author of this exciting new book is the inventor of the technology and a leader in the field. Following his step-by-step introduction, readers can start building aware/adaptive radios and then make steps towards cognitive radio. After an introduction to adaptive, aware, and cognitive radio, the author develops three major themes in three sections: FoundationsRadio CompetenceUser Domain Competence

The book makes the design principles of cognitive radio more accessible to students of teleinformatics, as well as to wireless communications systems developers. It therefore embraces the practice of cognitive radio as well as the theory. In particular, the publication develops a cognitive architecture that integrates disparate disciplines, including autonomous machine learning, computer vision, and language perception technologies. An accompanying CD-ROM contains the Java source code and compiled class files for applications developed in the book. In addition, for the convenience of the reader, Web resources introducing key concepts such as speech applications programmer interfaces (APIs) are included.

Although still five to ten years away from full deployment, telecommunications giants and research labs around the world are already dedicating R&D to this new technology. Telecommunications engineers as well as advanced undergraduate and graduate students can learn the promising possibilities of this innovative technology from the one who invented it.
