Cognitive Relay: Detecting Spectrum Holes in a Dynamic Scenario

Cognitive radio as first coined by Mitola in 1999 illustrates a dynamic model that provides human intervention to the underlying radio hardware. Dynamic spectrum access (DSA) is one of the many applications of cognitive radio. The DSA umbrella considers the secondary usage of the spectrum. On these grounds, we meant to design a working prototype for Cognitive Relay (CR), a device that dynamically accesses the spectrum to support wireless services operating indoor.
