Policy-driven Dynamic Spectrum Access (DSA) systems are emerging as one of the key technologies to enable the Department of Defense (DoD) to meet its increasing requirements for access to the electromagnetic spectrum. A key open issue surrounding deployment and continuing development of DSA systems concerns the need to test and evaluate the performance of DSA in avoiding interference to itself and assigned incumbent users and the performance of DSA network in the presence of various types of potential interference. In this paper, the authors describe test framework and concepts to characterize performance of DSA-enabled policy-based radios.
