Abstract

SCCL, a new bit tracking loop based on the sample-correlate-choose-largest design principle, was shown to be an effective bit synchronizer. However, the analysis common in analyzing digital phase locked loops, proceeds on the assumption that the noise samples are independent which is not necessarily true in practice. The performance of SCCL, is analyzed without the independence assumption by considering the second-order statistics to complete the analysis. This approach is also useful to analyze other digital phase-locked loops or baseband digital signal processing schemes in digital communication systems
