Summary:
The future global navigation satellite system uses high-ordered binary offset carrier (BOC) modulated spreading signals. By the way, it causes a narrower main lobe and multiple side lobes in correlation function. Thus, the serial search scheme, a well-known method for code acquisition, has a number of search cells to acquire the offset, and the time to first fix will also increases. To tackle this problem, we propose a rapid code acquisition scheme when the serial search scheme is used for high-order BOC modulated spreading signals.
