Abstract
A synchronization unit for performing fine synchronization in the Time Domain, the synchronization unit includes a storage configured to store reference signals. A multiplier capable of calculating sum of zero product shift, sum of minus one product shift, and sum of plus one product shift, based on the reference signals. A signal analyzer capable of computing left, center, and right cross-correlation points based on the sum of minus one product shift, the sum of plus one product shift, and the sum of zero product shift. A timing error estimation unit capable of estimating timing error of the received signal based on the left cross-correlation point and the right cross-correlation point. A phase estimation unit capable of estimating common phase error of the received signal based on the sum of zero product shift. A correlation level estimation unit capable of calculating correlation level indicative of a correlation between the received signal and a reflection of the received signal ghost based on the center point.
