GPS Enhanced Dynamic Spectrum Access

ABSTRACT: DSA and alternate positioning systems have natural synergies. Phase I will identify the most promising application(s) that leverage the synergies between DSA and alternate positioning systems, quantify and characterize expected performance, operational constraints, and limitations to those application(s) to show that the identified applications are feasible, design a prototype system in Phase II that will enable further study and development of the identified applications. BENEFIT: The results of this work could be applied to any DSA-enabled system to provide greater resiliency in the GPS-denied environments and greatly extending the deployment scenraios that positioning services could be deployed. This could be applied to 802.22, 802.11y, 802.11h and many other commercial DSA systems as well as military radio systems planning to integrate DSA.
