摘要
The present invention relates to an amplitude modulation apparatus, an amplitude limiting method, and a transmission apparatus for performing amplitude limitation on an orthogonally modulated signal. The amplitude modulation apparatus, the amplitude limiting method, and the transmission apparatus enable peak value suppression of a transmission wave with a simple structure. An amplitude limiting apparatus that performs amplitude limitation on an orthogonally modulated signal includes first amplitude limiting means (31, 32) for limiting to predetermined amplitudes the amplitudes of an I-component and a Q-component of the orthogonally modulated signal that are orthogonal to each other, and second amplitude limiting means (33-41) for performing further amplitude limitation on the I-component and the Q-component according to the difference between the amplitude-limited I-component and Q-component obtained by the first amplitude limiting means.
