摘要

与已有30年历史的L1 C/A信号一起，由现代化GPS计划提供的新信号L2C保证了民用GPS双频接收机的未来，它比目前的单频接收机具有更好的性能。本文介绍了一种针对GPS双频L1 C/ a和L2C接收机的新型组合采集方法。该方法充分利用了信号通道的容量和差分信号处理的优点。在合理的复杂度下具有较高的检测灵敏度是该方法相对于其他文献的主要优点。

A novel signal acquisition method for GPS dual-frequency L1 C/A and L2C receivers

Together with the 30-year-old signal L1 C/A, the new signal L2C, offered by the modernized GPS program, assures a future for civil GPS dual-frequency receivers which propose a better performance than the current single-frequency ones. This paper introduces a novel combined acquisition method dedicated to the GPS dual-frequency L1 C/A and L2C receivers. The method exploits the capacity of both the signal channels as well as the advantages of differential signal processing. High detection sensitivity at a reasonable complexity is the main advantage of the proposed method with respect to others in literature.
