Abstract

Binary offset carrier (BOC) modulation technology is widely used in newly developed and modernized global navigation satellite systems. BOC signal offers superior performance over conventional binary phase-shift keying signal due to its sharp auto-correlation function. However, the main drawback of BOC signal tracking is the ambiguity problem caused by the presence of multiple side-peaks in the auto-correlation function. We derive a new analytical model to solve the ambiguity issue. Based on the derived analytical model, a code tracking algorithm that completely removes all ambiguities is introduced. Theoretical analysis and simulation show that the proposed technique significantly improves the multipath mitigation performance and code tracking accuracy in thermal noise over those of existing side-peaks-cancellation techniques.
