Compensation for frequency offset in FDM receivers

A method and apparatus are provided for compensating for a frequency offset in an interleaved frequency division multiple access. The method compensates for a frequency offset between a transmission signal and a reception signal for a uth user (1≤ u ≤ U, where U denotes the number of users) The method includes: (a) estimating the frequency offset from a selection signal that is determined as the reception signal for the uth user in an initial mode and as a feedback signal in a normal mode; (b) estimating multiple access interferences representing an extent to which reception signals of other users interfere with the reception signal for the uth user; (c) subtracting the estimated multiple access interferences from the reception signal for the uth user and using the result as the feedback signal; (d) determining whether steps (a), (b), and (c) have been repeated a predetermined number of times, and if not, going back to step (a); and (e) if it is determined that steps (a), (b), and (c) have been repeated the predetermined number of times, estimating the transmission signal for the uth user using the feedback signal finally determined in step (c) and the estimated frequency offset.
