Abstract:
An OFDM transmitter and an OFDM receiver respectively transmit and receive N (N≥2, N is an integer) control symbols. For each control symbol, a guard interval time-domain signal is, for example, identical to a signal obtained by frequency-shifting at least a portion of a useful symbol time-domain signal by an amount different from any other symbol, or to a signal obtained by frequency-shifting one or both of a portion and a span of a useful symbol interval time-domain signal different from any other symbol by a predetermined amount.

Claim (Index 7):
An OFDM transmission device comprising:\n a control symbol generator that generates a first control symbol and a second control symbol such that the first control symbol includes a first useful part and a first guard interval part following the first useful part and that the second control symbol includes a second useful part and a second guard interval part preceding the second useful part, the first guard interval part being a copy of at least a portion of the first useful part with frequency shifted by a first amount, the second guard interval part being a copy of at least a portion of the second useful part with frequency shifted by a second amount, the second amount being different from the first amount; an information symbol generator that generates an information symbol different from the first control symbol and the second control symbol; a combiner that combines the first control symbol, the second control symbol, and the information symbol such that the second control symbol is provided between the first control symbol and the information symbol; and an OFDM signal generator that generates an OFDM signal based on the combined symbols.
