ABSTRACT:
An adaptive channel estimation method utilized in a multi-carrier communication system. The communication system transmits a symbol through a plurality of subchannels. The plurality of subchannels includes a plurality of pilot signal subchannels and a plurality of data signal subchannels. The pilot signal subchannels transmit a plurality of pilot signals of the symbol; the data signal subchannels transmit a plurality of data signals of the symbol. The method includes: categorizing each of the subchannels according to the relative position of each of the subchannels with respect to the pilot signal subchannels; determining channel responses of at least one of the pilot signal subchannels; and estimating channel responses of the data signal subchannels based on the channel responses of at least one of the pilot signal subchannels.
