CA 2315489

In a radio communication apparatus and method, on the transmitting side, an input signal is modulated in an intermediate frequency band to produce a modulated intermediate frequency band signal, a local oscillation signal is used to up-convert the modulated intermediate frequency band signal to a modulated radio frequency band signal, and the local oscillation signal and the modulated radio frequency band signal are simultaneously transmitted as a radio signal, and, on the receiving side, the radio signal from the transmitter is received, the received signal is down-converted by multiplying the local oscillation signal component and the modulated radio frequency band signal component contained in the received signal to generate a multiplication component and thereby produce a modulated intermediate frequency band signal, and the modulated intermediate frequency band signal is demodulated.
