Patent ID: 8320481

Claim:
A synchronization method used in a receiving terminal of an orthogonal frequency division multiplexing (OFDM) system, the synchronization method comprising: receiving an OFDM training symbol at the receiving terminal, wherein the OFDM training symbol comprises a plurality of sample points; calculating a plurality of first function values according to the sample points by using a first function; selecting D timing points from a plurality of timing points corresponding to the first function values, wherein D first function values of the first function values corresponding to the D timing points are all greater than a first threshold value, and D is a positive integer representing the number of the selected timing points; calculating D second function values of the D timing points by using a second function; and selecting one of the D timing points, and setting the selected one of the D timing points as a timing synchronization point, wherein the second function value of the selected one timing point is a first one greater than a second threshold value.
