Investigation of GPS Software Radio Performance in Combating Narrow Band Interference

Jason R. Burns, Curtis Cutright and Michael Braasch

Abstract:	Since the conception of GPS, interference (intentional or other wise) has been of major concern. The future of GPS depends not only on its accuracy, but also on its reliability under non-ideal circumstances. A software receiver allows flexibility in dealing with interference. The exploitation of spectrum transforms and other mathematical tools is sure to become more and more a focus of research as computational speeds increase. This paper explores the performance of the GPS L1 signal in the presence of Radio Frequency Interference (RFI). Of particular interest are the affects of differing numbers of quantization levels in the A/D (analog to digital) converter on interference mitigation performance of the Software Radio.
