摘要：A transmission apparatus for performing an orthogonal frequency divisionmultiplexing (OFDM) transmission generates an OFDM symbol in which a modulationparameter used at a time of transmitting data is arranged in a subcarrier of a direct

current component and transmits a transmission frame including the generated OFDMsymbol. A receiving apparatus calculates an average value in an effective symbol periodwithin the OFDM symbol included in the transmission frame received, extracts themodulation parameter arranged in the subcarrier of the direct current component basedon the calculated average value, and performs OFDM demodulation processing using theextracted modulation parameter.
