摘要
导航定位接收机中的相关器设计是导航定位接收机设计的一个关键技术,而相关器的设计将发展为基于SoC应用的IP核的设计。阐述了导航定位相关器的工作原理和结构,对构成相关器的各个模块进行了分析,并对Galileo/GPS的导航信号进行分析。在此基础上,采用基于SoC应用的IP核设计方法对Galileo/GPS双模相关器IP核进行设计,并进行了仿真验证和分析,可方便地应用于导航定位接收基带SoC的设计中。
The correlator design is a key technology in navigation receiver design,and the correlator will be designed to develop IP-based designs for SoC applications.This paper describes firstly the operation principle and structure of a navigation correlator.And then it analyzes various modules of the device and Galileo/GPS navigation signals.On this basis,Galileo/GPS dual-mode correlator IP-core design is implemented by IP-based SoC design method.The simulation results indicate that this design can be easily applied to the navigation and positioning receiver baseband SoC design.
