Abstract

Abstract

For the unambiguous general acquisition for Binary Offset Carrier (BOC) and its derivative signals is still scarce of analysis, a new unambiguous algorithm is proposed for all types of BOC signals and all kinds of modulation order. Firstly, the common sub-carrier model is constructed according to the links of different sub-carrier modulation. Then according to the common sub-carrier model the general expression of the signals is got. On this base, the sub-carrier is broken down into many half periods. Last, a general capture method based on a combined correlation function is proposed. Simulation results indicate that the proposed method can deal with all kinds of BOC modulated signals including complex ones with different phases or orders. An unambiguous correlated function can be obtained by the proposed method. The main peak width of correlated function is narrowed and the accuracy of capture is improved.
