| description | Provided is a channel estimating device, wherein the precision in channel estimation when the reception level has temporarily fallen down is improved. The channel estimating device has a channel-fluctuation detecting unit that assesses whether the fluctuation width of the level of the received signals is equal to or more than a threshold value, and whether the cycle of that fluctuation is equal to or less than a prescribed threshold value. The channel estimating device also has a channel estimating unit that assesses whether the decrease in the level of the received signal is temporary or not, by referring to the history of the level of the received signals, when the channel-fluctuation detecting unit assesses that the fluctuation width of the level of the received signals is equal to or more than the threshold value, and that the cycle of that fluctuation is equal to or less than the prescribed threshold value; and that lets the signal pass through without removing it as noise, even when the level of the rec |
