The Double Phase Estimator (DPE) has been recently proposed as an effective alternative to the Double Estimator
(DE) for unambiguously tracking Binary Offset Carrier (BOC) modulated signals. In the DPE, the signal subcarrier is
processed independently from the code and carrier components and it is tracked using a modified Phase Lock Loop (PLL). In the presence of signal bandlimiting, the DPE is able to generate local signal replicas better matched to the input components outperforming the DE.
In this paper, the performance of the DPE are further characterized and, in particular, the concept of Subcarrier Multipath Error Envelope (SMEE) is introduced and used to analyse the multipath performance of DPE and DE. The analysis confirms the advantages of the DPE in the presence of signal bandlimiting.
