The invention provides precise estimation of a channel response and correct demodulation of an information signal even in the circumstance of being likely suffering interference. The invention includes an error correcting code unit 1 , an S/P converting unit 2, a mapping unit 3, an IDFT (Inverse Discrete Fourier Transform) unit (IFFT: Inverse Fast Fourier Transform can be used) 4, a P/S converting unit 5, a GI (Guard Interval) inserting unit 6, preamble (A, B 0 , B 1 ) storage selecting units 11 -a and 11 -b, switch units 12 -a and 12 -b, D/A converting units 13 -a and 13 -b, radio units 14 -a and 14 -b and antenna units 15 -a and 15 -b. |
