Claim:
1. A radio communication apparatus comprising: a processor that generates a transmission signal on the basis of data to be transmitted, the processor generating the transmission signal by a transmission scheme selected from a digital transmission scheme and an analog transmission scheme, and a transceiver that transmits the transmission signal according to the selected transmission scheme, wherein the digital transmission scheme is a transmission scheme by which a bit stream obtained through binary encoding of the data to be transmitted is converted into the transmission signal, and the analog transmission scheme is a transmission scheme by which the data to be transmitted directly is converted into the transmission signal without performing binary encoding of the data to be transmitted, and wherein in response to the processor selecting the analog transmission scheme, the transmitted data includes channel information obtained through channel estimation of reference signals received by the radio communication apparatus, the channel information including each component contained in a channel response matrix or each component contained in a covariance matrix corresponding to a channel response matrix.
