PROBLEM TO BE SOLVED: To obtain good communication characteristics by providing an estimating means which estimates a remaining frequency offset from pilot information and the reference phase information, a reference phase information generating means which generates the corrected reference phase information from the estimated frequency offset. SOLUTION: A frequency offset correction part 11 estimates a frequency offset quantity from a known pattern of a burst head part and generates a signal S3 from which the offset is almost removed. This signal S3 is converted by a time axis-to-frequency axis conversion part 12 into a signal S4 on a frequency axis, which is sent to a detection part 13. A reference phase and amplitude regeneration part 14 generates reference phase and amplitude information S6 from the signal S4 on the frequency axis. A reference phase and amplitude correction part 15 generates reference phase and amplitude information S7 which is corrected equally to all subcarriers by referring to the pilot carrier embedded in the signal S4. The detection part 13 is therefore able to perform detection by using the corrected information S7, so excellent demodulation can be performed. |
