Abstract
Methods are presented herein for estimating at least a frequency (offset) for a block of received symbols using two or more estimation stages. These methods may allow reducing the computational complexity of a frequency estimator while maintaining large frequency offset coverage and high frequency estimation accuracy. Also presented herein are satellite communication systems employing a burst transmission or continuous transmission, and configured to estimate at least a frequency (offset) for a received burst or a block of received symbols using two or more estimation stages. In some embodiments, a received burst or a received block of symbols may include a Unique Word located at or about the center of the received burst or the block of symbols.
