Time recovery circuit and method for synchronizing timing of a signal in a receiver to timing of the signal in a transmitter

摘要

The present invention is a time recovery circuit and method for synchronizing timing of a signal in a receiver to timing of the signal in a transmitter. A plurality of samples of the early-late correlation difference are taken around the equilibrium point on the S-curve where the time error is zero. A recursive algorithm is used to compute the time adjustment necessary to time align the transmitter and the receiver by minimizing the squared estimation error.
