A communication apparatus and a channel estimating method for performing channel estimations with high precision. The communication apparatus, which receives multicarrier signals comprising a plurality of subcarriers, has a first estimating unit that generates temporary channel estimation values from pilot signals located in any ones of a plurality of received subcarriers; a second estimating unit that generates a virtual channel estimation value sequence related to the frequency bands other than the frequency bands of the plurality of subcarriers and that combines the generated virtual channel estimation value sequence with the plurality of temporary channel estimation values to generate a channel estimation value sequence corresponding to a predetermined frequency bandwidth; and a generating unit that uses this generated channel estimation value sequence to generate channel estimation values related to any ones of the plurality of subcarriers.
