Abstract:
1. A radio communication method comprising: generating a first transmit RF signal and a second transmit RF signal from a data signal to be transmitted, the first transmit RF signal and the second transmit RF signal respectively having a power spectrum in symmetric shape in the frequency domain; transmitting the first transmit RF signal and the second transmit RF signal at a different time from a single transmit antenna; receiving the first transmit RF signal and the second transmit RF signal to generate a first received RF signal and a second received RF signal; and reproducing the data signal only from the first received RF signal and the second received RF signal, wherein the generating the first transmit RF signal and the second transmit RF signal comprises: modulating the data signal to generate a first transmit baseband signal which has a first power spectrum; subjecting the first transmit baseband signal to a first computation to generate a second transmit baseband signal which has a power spectrum forming a symmetric shape with respect to the first power spectrum in the frequency domain; and subjecting the first transmit baseband signal and the second transmit baseband signal to an RF process to generate the first transmit RF signal and the second transmit RF signal.
