A novel time-varying Doppler frequency synthesizer
A novel time-varying Doppler frequency synthesizer is presented in this paper. Time-varying Doppler frequency synthesis is one of the most critical problems in high dynamic GPS signal simulator. The presented frequency synthesizer which may be easily implemented by software and hardware in digital domain can accurately control Doppler frequency and its derivatives of generated signals by means of designing inputting controlling words of carrier NCO, so as to accurately simulate received time-varying carrier Doppler frequency arising from high dynamics between satellites and GPS receivers. Experiment results confirm the correctness and validity of the proposed scheme.
