Abstract :
An algorithm is simulated and researched for direct acquiring PRN code based on the technology of band pass signal sub-sampling, utilizing the auto-correlation characteristic of the long period PRN code in BOC modulation. The algorithm is simulated and its performance is analyzed with decreasing Signal-to-Noise. The validity of the algorithm with the lower SNR is proved by simulation under band pass sub-sampling. The number of computing data is much less, because of the lower sampling frequency.
