摘要：
Adaptive modulation part (1) modulates a signal in a modulation scheme selected based on a modulation mode, switch (2) selects a radio scheme congenial to the modulation scheme in which the signal is modulated. When the selected radio scheme is single-carrier scheme, single-carrier generation part (3) generates a single-carrier signal. When the selected radio scheme is a multicarrier scheme, multicarrier generation part (4) generates a multicarrier signal, the generated single-carrier signal or multicarrier signal is converted into a carrier band signal by quadrature modulation part (5), and the converted signal is amplified by transmission amplifier (6).
