Abstract

In this paper, we analyze the characteristics of frequency spectrum and autocorrelation function of the signal in global navigation satellite system (GNSS) with binary offset carrier (BOC) modulation. We discuss the basic working processes of the traditional BOC acquisition algorithm and the one by using auto-correlation side-peak cancellation technique (ASPeCT). We also evaluate the effect of eliminating secondary peak and anti-interference performance of these two algorithms. We perform the simulation under Gaussian white noise and band-limited white noise. The simulation results show that the acquisition algorithm by ASPeCT has great advantage in the effect of side-peak cancellation and few advantages in anti-interference performance in Gaussian white noise and band-limited white noise environments.
