A channel estimation device in wireless communication in use of a plurality of subcarriers for communication, comprises: a first channel estimation section which performs channel estimation for each subcarrier based on pilot signals mapped to each subcarrier; a second channel estimation section which further estimates channels for each subcarrier using channel estimation values estimated by the first channel estimation section; and a channel selection section, which selects and outputs the first and second channel estimation values estimated by the first and second channel estimation sections, according to the subcarrier.
