Abstract
Cognitive radio has been proposed as a promising technology to solve today's spectrum scarcity problem. Cognitive radio is able to sense the spectrum to find the free spectrum, which can be optimally used by cognitive radio without causing interference to the licensed user. In the scope of the adaptive ad-hoc freeband (AAF) project, an emergency network built on top of cognitive radio is proposed. New functional requirements and system specifications for cognitive radio have to be supported by a reconfigurable architecture. In this paper, we propose a heterogenous reconfigurable system-on-chip (SoC) architecture to enable the evolution from the traditional software defined radio to cognitive radioKeywords
