Abstract
A method includes receiving first data corresponding to a first signal sampled at a first sample rate, decimating the first data to provide a second signal sampled at a second sample rate, and recovering a pilot signal from the second signal. The method also includes evaluating the pilot signal to determine an error value, where the error value is based on a comparison of a sample of the pilot signal to zero. The method also includes adjusting the second sample rate based on the error value.
