Abstract

The application of cognitive radio (CR) techniques to enable efficient utilization of spectrum is an area of growing interest. In this paper we describe the design and the functionality of a hardware CR prototype board aimed at providing a low cost mass production solution for networked cognitive radios. The CR prototype enables the development and investigation of spectrally efficient waveforms tailored for operation in the military 225-400MHz VHF/UHF bands, in the presence of interference.
