ABSTRACT:
QPSK modulated quadrature baseband signal generating section301generates a QPSK modulated quadrature baseband signal. 8PSK modulated quadrature baseband signal generating section302generates an 8PSK modulated quadrature baseband signal. Based on the modulation scheme determined information, in-phase component switching section304and quadrature component switching section305switch between the QPSK modulated quadrature baseband signal, 8PSK modulated quadrature baseband signal and pilot symbol to output to radio section306. Radio section306performs the predetermined radio processing on the baseband signal to output a transmission signal. The transmission signal is amplified in power amplifier307, and the amplified transmission signal is transmitted from transmission antenna309. It is thereby possible to take into account both the improvement in the data transmission rate, and the benefit and convenience in terminals.
