ABSTRACT:
A timing recovery circuit samples an input signal, correlates the resulting sample stream with a reference pattern at different timings, then compares the resulting correlation values with each other and with a threshold, and estimates a timing at which a peak correlation can be obtained. The peak correlation timing is estimated with a precision exceeding the precision given by the sampling period. The estimated timing can be used by a receiving circuit for bit synchronization, symbol synchronization, or frame synchronization, or to adjust the sampling timing.
