Abstract
A transmission device that generates a transmission identification signal indicating transmission identification information for identifying a transmission device that transmits an orthogonal frequency division multiplexing (OFDM) signal, and that injects a transmission identification signal at a lower level than an OFDM signal corresponding to data to be transmitted into all OFDM symbols of the OFDM signal. The reception device demodulates the OFDM signal after the injection of the transmission identification signal from the transmission device.
