PROBLEM TO BE SOLVED: To provide a radio communication system for stable communication even if a frequency-selectivity fading occurs. SOLUTION: A transmission path state estimating part 31 calculates frequency characteristics of a transmission path by performing discrete fourier transformation with a factor of a transversal automatic equalizer 23 that equalizes the transmission path of a reception signal. A multi-carrier setting part 32 sets a parameter of multi-carrier modulation for a carrier number, a carrier band, and a carrier frequency according to frequency characteristics of the transmission path that has been calculated. By this, even if a frequency-selectivity fading occurs, stable radio communication can be performed. COPYRIGHT: (C)2011,JPO&INPIT
