Abstract :
We present a description of contemporary performance evaluation approaches for spectrum sharing technologies (including dynamic spectrum access (DSA)/cognitive radios (CR)), and the perspectives of stakeholders with respect to shortcomings and resultant delayed field transition impacts. The shortcomings are examined to generate a set of desirable new attributes for more capable test and evaluation (T&E) systems and methods. Ongoing research and development (R&D) using the DYnamic Spectrum Environment emulator (DYSE) aimed at addressing these DSA/CR T&E shortcomings is described including a radar-Long Term Evolution (LTE) network sharing example, a TV whitespace sharing example using 802.22, and a position/navigation/timing (PNT) example with shared RF sources for communications and PNT.
