PROBLEM TO BE SOLVED: To provide a transmission/reception method and a receiver which achieve simplification of signal processing and reduction in a circuit scale and are suited to multicarrier transmission. SOLUTION: A transmitter performs orthogonal modulation of a plurality of carrier waves having frequencies represented by f<SB>n</SB>=2<SP>n</SP>f<SB>0</SB>(n=0, 1, ..., m) (f<SB>0</SB>is a fundamental frequency), and multiplexes the resulting carrier waves, to generate a multicarrier signal. The receiver performs sampling at a frequency four times as high as the highest carrier frequency contained in the multicarrier signal. The value I<SB>n</SB>of an I signal component is obtained by dividing the cumulative sum of sample data values s[2<SP>m-n</SP>2k](-1)<SP>k</SP>over a range from k=0 to k=2<SP>n+1</SP>-1 by 2<SP>n+1</SP>. The value Q<SB>n</SB>of a Q signal component is obtained by dividing the cumulative sum of sample data values s[2<SP>m-n</SP>(2k+1)](-1)<SP>(k+1)</SP>over the range from k=0 to k=2<SP>n+1</SP>-1 by 2<SP>n+1</SP>.
