Pseudo-Correlation-Function-Based Unambiguous Tracking Technique for Sine-BOC Signals

GNSS Signals Acquisition and Tracking in Unfavorable Environment

“…As illustrated in this figure, we observe that all the S-curves are very close except for small differences around the maxima and minima that do not influence the tracking process. Note that the procedure that is used herein is similar to those of step-chips and BOC-PRN structures [28], [56], [57]. Figure 10 shows the process of implementing the input tape and the intermediate frequency filtering that is common to all three variants of our proposed method.…”

Unambiguous Processing Techniques of Binary Offset Carrier Modulated Signals

“…As another example of the application of SC design framework, in this section we show the design process of an unambiguous code tracking technique named pseudo-correlationfunction-based unambiguous delay lock loop (PUDLL) (Yao et al, 2010b) which is applicable to any BOC(kn,n) signals. At tracking stage, because the discriminator characteristic curve is based on the first derivative of SCF, the requirement to the shape of SCF is more stringent than in acquisition.…”
