White Paper: Cognitive Radio Algorithm Development And Testing

By Greg Jue and Bob Cutler, Agilent Technologies

The term "cognitive radio" (CR) means different things to different people. However, most seem to agree that cognitive radios have, as a fundamental building block, the requirement to sense their environment. Specifically, they require spectrum and location sensing. Fast and accurate spectrum sensing is critical to dynamic spectrum sharing, whether for television (TV) whitespace, next generation (XG) radio, or land mobile radio (LMR) applications. As with most new technologies, CR technology brings with it new design and performance verification challenges. This article describes some of these challenges and introduces a new tool, the cognitive radio algorithm R&D testbed from Agilent Technologies.
