Abstract

A transmission device of the present invention includes a baseband waveform generator to generate a transmission signal by using a transfer function H₀(f) that is in a relation of a matched filter with a transfer function H₁(f) in an analog domain of a transmission side and a reception side connected through a wireless channel, and transmits the transmission signal generated by the baseband waveform generator.
