Realtime Implementation of L1-Band Software Radios

Abstract

Efforts over the last two years have been directed towards characterization of quantization error effects in software radio interference mitigation algorithms. A high fidelity GPS software signal simulator was constructed during the 2001-2002 time frame. This simulator emulated the UPS signal-in-space and the receiver front-end-processing including the analog-to-digital (AID) conversion process. The simulator allowed one to control precisely the scenario under investigation. Efforts over the past year have been directed towards validation of the simulation against actual collected data with interference present.
