Abstract  Abstract

A multiple-input and multiple-output (MIMO) transmission apparatus includes a modulation signal generating section and a MIMO transmitting section. The modulation signal generating section generates: (i) a first OFDM modulation signal in which a plurality of subcarriers include a subcarrier carrying a pilot symbol and a subcarrier carrying a data symbol in both a first time period and a second time period; and (ii) a second OFDM modulation signal in which the plurality of subcarriers include a subcarrier carrying a pilot symbol and a subcarrier carrying a data symbol in the first time period while in the second time period an in-phase component and a quadrature-phase component of every subcarrier included in the plurality of subcarriers are zero. The MIMO transmitting section transmits the first OFDM modulation signal from a first antenna and transmits the second OFDM modulation signal from a second antenna.
