Abstract:
1. An OFDM transmitting apparatus comprising: an inserting section configured to insert a propagation path estimation signal into a plurality of user data; an OFDM signal forming section configured to form a plurality of OFDM signals from the plurality of user data and from the propagation path estimation signal; and a plurality of transmitting sections configured to transmit the plurality of OFDM signals from a plurality of antennas, wherein, when both of the propagation path estimation signal and the plurality of user data are to be transmitted simultaneously in a same symbol interval, the propagation path estimation signal is transmitted from one antenna by using a specific subcarrier, and the plurality of user data are transmitted from the plurality of antennas by using only subcarriers other than the specific subcarrier.
