This paper proposes a fast unambiguous acquisition technique for BOC-modulated signals. We remove the ambiguities (side-peaks) of the BOC autocorrelation function, exploiting a reduced-complexity (real and symmetric) filter composed of only 7 non-zero samples. The proposed scheme is applicable to both generic sine and cosine-phased BOC signals. Theoretical and simulation results show that the proposed method removes the ambiguities in the acquisition problem, without requiring any auxiliary signal in the receiver.
