    摘要： Channel estimation values of pilot symbols for channel compensation of data symbols in an OFDM receiver can be used, even in cases where FFT extract position differs for each frame. The OFDM receiver is characterized in having a circuit which calculates the amount of phase rotation that is generated by the difference in timing at which the individual symbols are extract as objects of a fast Fourier transform when the fast Fourier transform processing is performed by a fast Fourier transform circuit, and further a circuit which corrects the amount of phase rotation for the channel estimation value determined by a channel estimating circuit.

    摘要： A system performing communication by using a plurality of antennas is presumed to transmit a frame from an antenna 1 by structuring slots 1 and 2 in the frame, and another frame from an antenna 2 by structuring slots 3 and 4 in the frame. A reception side examines a presence or absence of an error for each slot. Assuming that there is an error in the slots 1 and 4, the reception side notifies the transmission side of information on the existence of errors in the slots 1 and 4. The transmission side embeds the slots 1 and 4 in a frame made up of two slots and retransmits the slots 1 and 4 respectively from the antennas 1 and 2.
