5. A transmission device that performs wireless communication with a reception device by using n (n≥2) frequency channels, the transmission device comprising:
a conversion unit that converts n+1 signals into n predetermined power signals obtained by setting a carrier-to-noise ratio (C/N) to a predetermined value and into n divided signals obtained by setting the C/N to 1/n of the predetermined value and performing division into n;
a superimposition unit that superimposes the n predetermined power signals and the n divided signals converted by the conversion unit non-orthogonally so as to be n multiplexed signals for the n frequency channels; and
a transmission unit that simultaneously transmits the n multiplexed signals obtained by superimposing by the superimposition unit by the n frequency channels.
