1. A communication system comprising:
- a first communication device configured to output a data signal;
a second communication device configured to generate a timing signal to control sampling of the data signal, to receive the data signal and to accumulate a history comprising error information during a first portion of the data signal and to adjust a timing signal during a second portion of the data signal using the history comprising the error information to synchronize the timing signal with the data signal; and
wherein the second communication device is configured to detect the error information comprising misalignment of the data signal and the timing signal.

Abstract
The present invention includes bit synchronizers and methods of synchronizing and calculating error. One method of synchronizing with a data signal in accordance with the present invention includes providing a data signal having a first portion and a second portion, generating a timing signal, first adjusting the timing signal during the first portion of the data signal, accumulating a history value during the first portion of the data signal, and second adjusting the timing signal during a second portion of the data signal using the history.
