GPS Enhanced Dynamic Spectrum Access

ABSTRACT: Echo Ridge and partner Wright State University (WSU) propose to develop and evaluate novel performance enhancing signal processing algorithms enabled by dynamic spectrum access (DSA)-based cognitive radio (CR) and GPS navigation functionality operating on a common software defined radio (SDR) platform in a cognitive network (CN) (Elemental SDR-hosted Cross Application Performance Enhancements, ESCAPE). We will exploit functionality and information traditionally present in each organic application to provide mutual-benefit through tightly coupling measurements in the multifunction common SDR-cognitive network context. ESCAPE benefits will include improved communications and reduced primary user (PU) interference performance for DSA radios, improved position, velocity and time (PVT) performance for GPS, and improved robustness to unintentional and intentional interference for both applications. The development and evaluation activities produce both a comprehensive trade space-based review of performance enhancing options, and a detailed evaluation of specific algorithms with the greatest technical merit.
