In a reception method and a receiver, a base station corrects a frequency offset contained in a reception signal from each user terminal and realizes excellent reception characteristics by using a simple receiver mechanism for performing frequency domain processing in a radio system using a frequency division multiplex (FDM) method. The base station includes: a DFT section that converts reception signals from a plurality of mobile stations communicating by radio communication using FDM all at once into the frequency domain; a demapping section that recognizes, from the frequency domain signals, user signals corresponding to respective mobile stations by using sub-carriers selected in association with respective mobile stations; a correction signal generation section generating a correction signal correcting a user signal frequency offset for each user signal; a frequency conversion section that corrects the frequency offset of the user signal by the correction signal; and a demodulation section that demodulates each of the corrected user signals.
