BOC调制方式提升了导航信号的性能和频谱资源利用率，但是自相关函数的多峰特性使信号接收面临新的问题。本文研究高阶BOC调制方式及其无模糊跟踪技术，主要分析了Bump-Jump算法、BPSK-like算法、SCPC算法和双环路算法，比较不同跟踪技术的硬件复杂度、计算复杂度、跟踪精度和跟踪稳定性，结果可为接收机设计提供参考。

The binary offset carrier(BOC) modulation signal provides enhanced satellite navigation service and good spectral compatibility ,but its autocorrelation function contains multiple peaks which presents a technical challenge to the signal tracking .This paper sum-marizes the features of BOC modulated signal ,and several unambiguous tracking methods such as the Bump-Jump method , the BPSK-like method , the SCPC method and the DET method are discussed on their hardware complexity ,computational load ,tracking accuracy and tracking robustness ,the results can provide reference for the receiver design .
