| Abstract: | 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 . |
