PURPOSE: A method and an apparatus of estimating a frequency offset based on training symbols in a wireless communication system are provided to improve estimation performance of the frequency offset under various noise environments including non-normal distribution noise as well as normal distribution noise. CONSTITUTION: A method of estimating a frequency offset based on training symbols in a wireless communication system comprise of: receiving signals comprising N samples(S101); obtaining N/2 samples from the received signals(S102); summing the N/2 samples(S103); finding an angle from the sum of N/2 samples(S104); and calculating an offset estimate based on the angle(S1050). [Reference numerals] (AA) Start; (BB) End; (S101) Step of receiving input signals; (S102) Step of obtaining N/2 samples from the received signals; (S103) Step of summing the N/2 samples; (S104) Step of finding an angle from the sum signal of the N/2 samples; (S105) Step of calculating an offset estimate from the found angle;
