A radio communication method, a radio transmission apparatus, and a radio reception apparatus are provided to reduce the power consumption and decrease the size of circuits. A transmission apparatus comprises a transmitter(201) for generating a first transmit RF signal and a second transmit RF signal from a data signal to be transmitted, and then outputs the RF signals at a different time. Herein, each of the first transmit RF signal and the second transmit RF signal has a symmetrical power spectrum in a frequency domain. The transmission apparatus further comprises a transmit antenna(202) for transmitting the first transmit RF signal and the second transmit RF signal. A radio reception apparatus comprises a receiving antenna(204), an RF reception unit(221), a channel equalizer, a computing unit, a combiner, and a demodulator(222). The receiving antenna receives the first transmit RF signal and the second transmit RF signal to obtain a first received RF signal and a second received RF signal. The RF reception unit performs an RF process on the first received RF signal and the second received RF signal to generate a first received baseband signal and a second received baseband signal. The channel equalizer performs a channel equalization process on the first received baseband signal and the second received baseband signal to obtain a first equalized baseband signal and a second equalized baseband signal. The computing unit performs a computation process on the second equalized baseband signal. The combiner combines the second equalized baseband signal after computation and the first equalized baseband signal to obtain a combined baseband signal. The demodulator demodulates the combined baseband signal to reproduce the data signal. |
