NSF Award #2229427, 2229428: We are developing, implementing, and testing methods to share spectrum reliably with passive radio users, like radio telescopes, by providing new feedback & accountability mechanisms, which we call "pseudonymetry". With a secure and reliable feedback mechanism, we can handle the worst-case interference and design sharing systems for the average case. Our work hopes to increase the efficiency of use of valuable spectrum resources, which are important for multiple scientific, government, and commercial purposes, without allowing interference between users. We are experimenting on the POWDER testbed as well as at the Owens Valley Radio Observatory.
