<p>Disclosed are a signal receiving method in a wireless communications system and a device thereof. The signal receiving method includes: a step of recognizing the start point of a frame based on a received signal; a step of recognizing the start point of fast Fourier transform based on the start point of the frame; a step of resetting the start point of fast Fourier transform for the start point of the fast Fourier transform to be placed on a cyclic prefix based on a predefined offset value; a step of performing fast Fourier transform based on the reset start point of fast Fourier transform; and a step of performing phase compensation on the result of fast Fourier transform against the predefined offset value. By doing so, it is possible to prevent deterioration of channel estimation performance.</p> |
