A Real Time Cognitive Radio Test Platform for Public Safety Physical Layer Experiments
Peter J. Green, Desmond P. Taylor · 2007
This paper describes the concept, architecture and development of a real time, cognitive radio testbed for physical layer, interoperability and spectrum sensing experiments. It is based on a reconfigured wireless 4-transmit 4-receiver multiple input and multiple output (MIMO) smart antenna software radio test system (SASRATS) platform using the the Xilinx University Program (XUP) Virtex-II Pro development boards as the heart of the system. We discuss various cognitive experiments in the context of public safety applications and show that cyclo- stationarity can be used for spectrum sensing and recognition applications.
