ABSTRACT:
A frequency offset correction value estimation section (21) receives a signal including a predetermined fixed pattern from a transmission side, thereafter, selects a combination of fixed patterns used in a process of estimating a frequency offset is selected depending on the state of a channel, and an estimation result of the frequency offset calculated by the combination of the fixed patterns is output as a correction value of a determined frequency offset. A frequency offset correction section (22) receives the received signal obtained after the correction is performed for correcting a frequency offset of the received signal on the basis of the correction value, and an equalizer (23) demodulates the received signal by using a predetermined algorithm.
