为了克服原有抗多径算法在偏移二进制载波( BOC)信号上性能不如粗捕码( coar se/ acquisition co de, C/ A 码)的缺点, 并消除 BOC信号在跟踪时特有的多峰模糊特性, 将一种

新的参考码应用在 BOC信号的跟踪中,并与窄相关器以及高分辨相关器( HRC)技术进行了比较, 分别给出了多径误差包络, 从仿真结果中得出了最佳参考码码型,并根据最佳参考码

分析了成形( Shaping) 相关器的噪声性能。Shaping 相关器消除了多峰模糊的特点,并在多径误差包络上要优于窄相关器以及HRC 算法,也很容易在原有基础上修改实现。该研究为未来的导航接收机中 Shaping相关器的应用打下了坚实的基础。-Abstract: Exis tin g algorithm s are worse when applied to binary

offset carrier ( BOC) signals than for the coarse/ acquisition ( C/ A)

code in GPS receivers. Th is paper pres ent s a new ref erence code f or

BOC s ignal t racking and gives the multipath error envelope compared

to the narrow correlat or method and high resolut ion correlat or. The

best reference code is determined by simulations and the noise

performance of the best reference code is analyzed. The mult-ipeak

fuzzyness is cancelled by a Shaping correlator. The performance of

the Shaping correlator ps multipath mitigaion is better than the

narrow correlator and the high resolution correlator.This correlator is easy to realizes　the Shaping correlat or can be easily used in

future n avigat ion receivers.
