摘要
在基于对Galileo系统中BOC信号的基本特性分析以及基于E1信号的信号模型建立的基础上,对目前流行的几种捕获算法进行了介绍,并提出了一种基于能量搜索的两路相干的对Galileo E1-BOC信号的捕获算法,并对其进行了仿真。仿真结果表明,该方法不仅具有更好的灵敏度指标,而且也能减小其频率搜索数目。
On analyzing the basic characteristics of BOC signal and building the signal modeling of E1 in Galileo system,several popular acquisition algorithms are introduced.A two-way coherent acquisition algorithm on Galileo E1-receiver BOC signal based on energy search is proposed and simulated.Simulation results show that the method has better sensitivity index,and the number of frequency search can be reduced.
