This paper gives a complete map of building a cognitive radio. It goes through architecture definition, functional block building, system integration, and finally to a fullyfunctional CR node prototype that can be directly packaged for application use.

In our CR solution, a platform independent CR system architecture is defined with a software algorithm package called a cognitive engine (CE) with a general radio interface. Within the CE different functional modules are defined to realize cognitive capabilities including awareness, reasoning, solution making and optimization, and adaptive radio control. Based on this general CR solution, we present an application specific CR node prototype for public safety communication interoperability.
