Abstract:
1. A radio communication apparatus comprising: a first antenna and a second antenna; a first conversion section that converts an input signal to a frequency domain to obtain a plurality of frequency components of the input signal; a measuring section that measures, for each of the plurality of frequency components, a first propagation path quality of the first antenna and a second propagation path quality of the second antenna; a weighting section that weights each of the plurality of frequency components, using a first weighting factor, to obtain a first plurality of weighted frequency components, and weights each of the plurality of frequency components, using a second weighting factor, to obtain a second plurality of weighted frequency components, the first weighting factor and the second weighting factor being set in accordance with the first propagation path quality and the second propagation path quality; a second conversion section that converts the first plurality of weighted frequency components to a time domain to obtain a first transmit signal, and converts the second plurality of weighted frequency components to the time domain to obtain a second transmit signal; and a transmitting section that transmits the first transmit signal and the second transmit signal from one or both of the first antenna and the second antenna.
