Patent ID: 8467462

Claim:
A receiving apparatus receiving an OFDM signal, the receiving apparatus comprising: a Fourier transformation section configured to transform a channel estimation signal received by one reception antenna into a frequency domain; a channel estimating section configured to estimate a plurality of pieces of channel state information from the channel estimation signal transformed into a frequency domain by the Fourier transformation section and outputs the information; a multiplying section configured to multiply the plurality of pieces of channel state information by different codes; an adding section configured to add signals multiplied by the codes; and a demodulating section configured to demodulate the OFDM signal using a result of the addition, wherein: the plurality of pieces of channel state information is channel state information between a plurality of transmission antennas and the one reception antenna, and the different codes correspond to the plurality of transmission antennas respectively, and are multiplied respectively by the signals that are sent from the plurality of transmission antennas.
