SATELLITE DOPPLER RATE COMPENSATION |
摘要 |
A telecommunications system includes a satellite receiver programmed to estimate a Doppler frequency associated with a satellite signal. Estimating the Doppler frequency includes sampling the satellite signal, resampling the sampled satellite signal, and compensating for a frequency offset associated with the satellite signal. An example satellite receiver includes a sampling device programmed to sample the satellite signal, a resampling device programmed to sample the sampled satellite signal and output a resampled satellite signal, and an incremental phase modulator programmed to filter a frequency offset from the resampled satellite signal. |
