Abstract
The integrity of navigation signal can be reflected on the correlation curve, so the quality of the signal can be evaluated by analyzing the correlation curve of navigation signal. Aiming at the binary offset carrier (BOC) modulation used in the navigation signal, and Taking BOC (1,1) as an example, the acquisition and tracking algorithm of the BOC signal is given first in this paper. Then the software receiver based on the multi-correlator is designed, and the performance of the correlation curve is analyzed from the aspects of pseudo-range difference value, multiple correlation value difference and multiple correlation value symmetry. The simulation results show that the BOC signal synchronization method proposed in this paper can be effectively captured and tracked, and the output results of the multi-correlator can accurately reflect the quality performance of the navigation signal, so it is suitable for signal quality assessment of BOC receiver.
