Abstract:
A method and apparatus for recovering an estimated velocity of a mobile station in a communication system are provided. The apparatus includes a searcher for determining a Doppler shift value representing the estimated velocity of the mobile station by using a channel impulse response of a preamble signal received at a regular interval of time, a detector for determining a reference Doppler value for compensating the Doppler shift value by using correlation ratios between channel values of symbols to which data for the mobile station are allocated according to subcarriers in a data allocation field of a frame including the preamble signal, and a compensator for determining a compensated Doppler shift value by using the reference Doppler value to compensate the Doppler shift value for a folding value, wherein the folding value represents a difference between the estimated velocity and a true velocity of the mobile station.
