| Abstract: | In this paper, the definition of BOC modulation is introduced, and the relationship between the Cremer- Rao limit of the thermal noise errors of BOC modulated PN code tracking and the modulation parameters is studied. The results drawn provide theoretical guidance for the design of BOC modulation parameters. The theoretical errors of PN code tracking in the GPS receiver and the Galileo receiver are respectively analyzed, which can provide reference for the evaluation of the PN code tracking algorithms of the GPS receiver and the Galileo receiver. |
