Abstract
The present invention provides a method and apparatus for correcting symbol timing of a receiver. The receiver receives a signal transmitted by a transmitter based on a symbol period. The method includes: sampling the signal with a sampling period to generate N sampled data in series, wherein the sampling period is half the symbol period; from Kth data of the N sampled data, getting M data to serve as a first data set; performing a timing recovery algorithm upon the first data set to generate a first timing metric; from (Kth+1) data of the N sampled data, getting M data to serve as a second data set; performing the timing recovery algorithm upon the second data set to generate a second timing metric; and correcting the symbol timing according to the first and second timing metrics.
