Abstract
A frequency offset synchronizer is provided which includes an initial timing estimator, and a combined frequency offset and refined timing estimator. The initial timing estimator determines a rough timing value from input data samples and a reference synchronization word. The combined frequency offset and refined timing estimator operates in the close vicinity of the rough timing estimate and determines the frequency offset and synchronization timing from the input data samples and the reference synchronization word.
