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 5):
An OFDM transmission method, comprising:\n generating 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; generating an information symbol different from the first control symbol and the second control symbol; combining 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 generating an OFDM signal based on the combined symbols.
