This paper describes our design and proof-ofconcept implementation of the Secondary User-Enhanced Spectrum Sharing (SUESS) radio that dynamically observes, understands, learns, plans, and adapts its spectrum sharing behaviors in an operating band that is shared with a noncooperative Primary User (PU) radio link. The SUESS radio leverages awareness of the PU's performance to drive the selection and adaptation of three spectrum coexistence mechanisms that include the Electromagnetic (EM), Physical (PHY), and Medium Access Control (MAC) protocol layers. Our goal is to design and build a prototype of a software-defined cognitive radio that maximizes throughput of the SUESS radio link while minimizing performance impact to a PU link in a shared RF operating band at short separation distances.
