Abstract
A method for symbol timing synchronization is provided. The method comprises the following steps. First, a correlation between a sample sequence and a delayed sample sequence is calculated to generate a correlation sequence. Wherein, the delayed sample sequence is obtained from delaying the sample sequence by N sampling points, and N is the length of the useful data for a symbol in the sample sequence. Then, a moving average of the correlation sequence is calculated to generate a cross-correlation sequence, and the cross-correlation sequence is differentiated to generate a differentiated sequence. Finally, a moving average of the differentiated sequence is calculated to generate a moving-averaged sequence, and the peak position of the moving-averaged sequence is detected in order to obtain the correct symbol timing for synchronization.
