Cross-correlation function based multipath mitigation technique for cosine-BOC signals

摘要

We propose a new multipath mitigation technique based on cross-correlation function for the new cosine phased binary offset carrier(cosine-BOC) modulated signals, which will most likely be employed in both European Galileo system and Chinese Compass system. This technique is implemented to create an optimum cross-correlation function via designing the modulated symbols of the local signal. And the structure of the code tracking loop for cosine-BOC signals is quite simple including only two real correlators. Results demonstrate that the technique efficiently eliminates the ranging errors in the medium and long multipath regions with respect to the conventional receiver correlation techniques.
