摘要
In this letter, a new unambiguous tracking technique is proposed for binary offset carrier (BOC) modulated signals, which will be utilized in global navigation satellite systems (GNSS). The proposed technique is a synthesized correlation function obtained by subtracting the cross-correlation between the received BOC signal and the local auxiliary signal from the cross-correlation of BOC signal between another local auxiliary BOC signals. The theoretical standard tracking error formulas are given. The results show that this technique can be a solution to remove the ambiguity completely with slightly degradation in acquisition and tracking for low modulation order BOC signals.
