BOC调制信号捕获的研究

Research on Capture of BOC Modulation Signal

由于BOC调制信号是一种非常新的调制信号,在伽利略系统中占据着重要地位,因此对它的捕获研究就显得尤为重要。而本文正是研究了BOC调制信号的捕获技术。首先,介绍了BOC调制中的相关器;其次,分析了BOC调制信号的捕获技术;最后,对BOC调制理论进行了仿真实验。结果表明:BOC调制信号均值法捕获可以很好地捕获到信号,达到了预期要求。

Beacause the BOC modulation is a very new modulation,it occupies an important position in the Galileo system,so it is very important to study the modulation.This article is the research on the capture of BOC modulation.First of all,the article introduces the correlator of BOC modulation;it analyzes the capture technology of BOC modulation;at last,the simulation experiment of BOC modulation theory is carried out.The results show that averaged numerical capture can capture BOC modulation signal very well,and it can achieve the expected requirement.
