Patent ID: 8516328

Claim:
A reception method adapted to a reception device receiving wireless signals in a multicarrier wireless communication system adopting forward error correction codes, which transmits and receives wireless signals constituted of a plurality of sub-carriers, said reception method comprising: an interference band detection process for selecting sub-carriers causing reception errors from among the plurality of sub-carriers by way of specific sub-carriers; a weight coefficient generation process for generating weight coefficients, reducing reliability in sub-carriers, not depending on a power ratio (i.e, a D/U ratio) between a desired wave and an interference wave, with respect to the selected specific sub-carriers compared to other sub-carriers; a demodulation process for demodulating the received wireless signals of sub-carriers; a weighted calculation process for performing weighted calculation applying the weight coefficients to demodulated values of sub-carriers of wireless signals; and a decoding process for performing a decoding process for error correction on calculated values of sub-carriers.
