摘要
介绍了BOC调制的定义,研究了BOC调制伪码跟踪热噪声误差Cremer-Rao界与调制参数之间的关系,所得结论可为BOC调制信号参数设计提供理论指导。分析了GPS和Galileo接收机伪码跟踪热噪声的理论误差,可为GPS和Galileo接收机伪码跟踪算法性能评价提供参考。
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.
