Description
Summary:To overcome the acquisition problems caused by the multiple peaks of the auto-correlation function of Binary Offset Carrier (BOC) modulated signal, a technology is proposed in this paper to eliminate secondary peaks based on sub-combination correlation. According to the characteristics of the sub-function of the BOC autocorrelation function, this new method recombining the sub-correlation function obtains the ability to eliminate the edge. In the process of local design, it is aimed to design two local signal waves which can achieve the homologous sub-correlation function of BOC auto-correlation function by respectively correlating both local and received signals. MonteCarlo simulations show that the proposed method can improve 3 dBHz sensitivity in detection probability compared with ASPeCT when the non-coherent number is 10 for BOCs (1, 1). In addition, it can be applied to BOCc (1, 1) and achieve the same the detection probability compared with the traditional BSPK-LIKE method by appropriately increasing the number of non-coherent.
