摘要：
A method for improving time synchronization of digital data signals in receivers by using more than one known data sequence to provide a plurality of timing recovery functions and based on these, one or more optimal sampling points. By using existing data sequences in each frame, the disclosed method provides improved time synchronization without increasing transmission overhead.
