Abstract:
An apparatus and method for correcting a CPE in a signal reception apparatus of a multi-carrier communication system are provided, in which an auto-correlation of a reference signal estimated from a reference symbol among a plurality of symbols is detected, a cross-correlation between a channel estimate of the reference signal and an actual received reference signal is detected, and the CPE of the remaining symbols except the reference symbol is corrected using the auto-correlation and the cross-correlation.
