ABSTRACT:
A digital baseband modulation apparatus includes: a spread modulation part for complex spreading an I component signal and a Q component signal of a send signal so as to output an output signal; and an amplitude conversion part for decreasing the amplitude component of the output signal to the half when the output signal is output on the I axis or on the Q axis.
