Abstract
A method, apparatus and system for estimating frequency offset that includes: a first calculating unit to calculate a correlation value of each of multiple sequences with different lengths according to a received signal containing the sequences with different lengths, where each of the sequences is repeatedly transmitted many times in the signal; a second calculating unit to calculate a decimal frequency according to the correlation value; a first determining unit to determine an integer frequency offset according to the decimal frequency offset to which each of the sequences corresponds; and a second determining unit to determine a total frequency offset according to the decimal frequency offset and the integer frequency offset.
