Abstract
Disclosed are methods and apparatuses for receiving signals in a wireless communication system. The method may comprise identifying a frame start point based on a received signal; determining a fast Fourier transform (FFT) start point based on the frame start point; reconfiguring the FFT start point in order for the FFT start point to be located within a cyclic prefix (CP) period based on a preconfigured offset value; performing FFT based on the reconfigured FFT start point; and performing, on a result of the FFT, a phase compensation based on the preconfigured offset value. Thus, degradation of channel estimation performances can be prevented.
