PROBLEM TO BE SOLVED: To provide a receiving device that uses a scattered pilot signal and is able to accurately perform DC offset estimation and transmission path estimation in a communication system in which the time and frequency direction change precipitously.SOLUTION: In the invention, part of a scattered pilot signal is placed on a DC component of a frequency signal S-651 as a communication signal. A pilot transmission path estimation unit 666 estimates a pilot transmission path estimation value S-6661 on the DC component on the basis of transmission path gain S-6621 other than the DC component and a corresponding table selected by a table selection unit 664. |
