Abstract
The present invention relates to an interference power estimating device that estimates interference power with high accuracy. The interference power estimating device includes a reference symbol acquiring unit acquiring a reference symbol corresponding to each of the pilot symbols included in a received signal by symbol-averaging a reference signal including the pilot symbol being allocated in positions near in terms of time to each of the pilot symbols and having the number less than the number of the pilot symbols within one slot, and an estimating unit estimating interference power of the received signal by power-valuing each difference between each of the pilot symbols and the reference symbol corresponding to each of the pilot symbols acquired by the reference symbol acquiring unit.
