摘要
Abstract
Alternate Binary Offset Carrier (AltBOC) signal is a new navigation signal on the E5 frequency of Galileo system. This signal includes double side-band, E5a and E5b, and modulates four independent navigation signals. The traditional acquisition technology usually adopts one signal and 25% total signal power, which influence the acquisition performance. On the basis of single side-band acquisition, two methods of double side-band non-coherent combination acquisition and double side-band coherent combination acquisition are used, and the theory analysis is performed. The simulation validates the performance of these schemes.关键词
