A transmission device ( 100 ) includes a differential encoding section ( 101 ) for differentially encoding transmission data, a first waveform generation section ( 102 ), a second waveform generation section ( 103 ), and two transmission antennas ( 109 and 110 ). A reception device ( 140 ) includes a reception antenna ( 141 ), a delay detection section ( 144 ), and a data determination section ( 145 ) for low-pass filtering a delay detection signal. The reception device ( 140 ) receives modulated signals modulated by using two wave forms having low correlations with each other. Thus, regardless of the presence or absence of delay dispersion in a propagation path and even in a high-speed fading in which the propagation path varies at high speed, a transmission diversity effect can be achieved, thereby making it possible to improve transmission characteristics.
