Abstract：An unambiguous acquisition scheme for BOC (m,n) signals is proposed by constituting a Synthesis Supplemental Correlation Function (SSCF) according to their features. By applying the proposed scheme, side peaks are well eliminated and an unambiguous correlation function with a single narrow peak is obtained. It is confirmed that the proposed scheme is capable of acquiring BOC (m,n) signals. It is especially compared with the traditional BPSK-like method and the results show that the SSCF scheme performs much better in the acquisition success rate and peak-to–average ratio despite the noise interference.
