N2 - To tackle the problem of ambiguous acquisition of Binary Offset Carrier (BOC) signal induced by more than one auto-correlation peaks, this paper proposes a novel unambiguous acquisition algorithm based on quadratic BOC (QBOC). In the proposed algorithm, two local QBOC auxiliary signals with different phase are first correlated with received signal, respectively. Then, by combing two cross-correlations, a correlated function with single peak is obtained, followed by the signal acquisition. The proposed algorithm is able to eliminate the ambiguity of the correlation function completely for arbitrary order of the BOC modulated signals and improve the value of main peak. Furthermore, compared with other methods, the proposed algorithm has better acquisition performance. Theoretical and simulation results verify the effectiveness of the proposed algorithm.
