Abstract:
1. A channel estimation device in wireless communication with use of a plurality of subcarriers for communication, comprising: 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 performs channel estimation for each subcarrier using channel estimation values estimated by the first channel estimation section; and a channel selection section which selects and outputs first and second channel estimation values estimated by said first and second channel estimation sections, according to the subcarrier, wherein said second channel estimation section includes: wherein said channel selection section selects the channel estimation values estimated by said first channel estimation section as channel estimation values for subcarriers at both ends of an effective band, selects the channel estimation values estimated by said second channel estimation section as channel estimation values for subcarriers other than the subcarriers at both ends of the effective band, and outputs the selected values.
