摘要： A method for estimating a frequency difference between a transmission terminal and a reception terminal according to a reception signal is provided. The method includes steps of: in a first period, receiving and storing a first part of the reception signal; in a second period, frequency shifting the first part of the reception signal according to an L number of sweep frequencies, and correspondingly obtaining multiple first part correlation results, where L is a positive integer; in the second period, receiving and storing a second part of the reception signal; in a third period, frequency shifting the second part of the reception signal according to the L number of sweep frequencies, and correspondingly obtaining multiple second part correlation results; and estimating the frequency difference according to the first and second part correlation results.
