Abstract :
Global Positioning System (GPS) receivers that must operate under fading propagation conditions can use differential phase-shift keying (DPSK) and reference bits to reliably demodulate GPS data. The demodulation performance of such receivers is analyzed for nonfading and Rayleigh fading channels. Theoretical results derived here are compared with measured error rates taken during scintillation testing of a prototype GPS/DPSK receiver.
