A Flexible Hardware Platform for Mobile Cognitive Radio Applications

The European FP7 QoSMOS project aims to demonstrate a Cognitive Radio (CR) system in the White Space (WS). A new flexible hardware platform has been designed and implemented to validate several scenarios involving a framework for Quality of Service and mobility. These scenarios will be demonstrated in the Television WS (TVWS), which is the first band opened to CR overlay networks. This paper describes the requirements for the platforms and points out the limitations of off-the-shelf hardware solutions. Then the architecture of the new platform is described, its performance is compared and its flexible features are described.
