Mitola Joseph, III. Cognitive Radio Architecture: The Engineering Foundations of Radio XML

John Wiley & Sons, Inc., 2006. — 488 p.This book is about making radios so smart that they can autonomously discover how, when, and where to use radio spectrum to obtain information services without having previously been programmed to do so. Cognitive radio integrates machine perception software into wireless systems—radio nodes and networks. Radios today are evolving from awareness (e.g., of location) toward cognition: the self-aware radio autonomously learns helpful new wireless information access and use behaviors, not just sensing the radio frequency (RF) spectrum but also perceiving and interpreting the user in the user’s environment via computer vision, speech recognition (speech-to-text), and language understanding.
