PROBLEM TO BE SOLVED: To provide a communication system capable of suppressing the reduction of communication quality caused by the fluctuation of a multiplex timing which occurs when multiplexing a plurality of signals in a time division manner. SOLUTION: A transmission delay correcting signal generating circuit 14 measures a delay profile of a first OFDM signal included in a transmission signal STX and a delay profile of a second OFDM signal similarly included in the transmission signal STX, measures a deviation timeΔt between multiplex timings in a multiplexing part 13 on the basis of the measured two delay profiles and transmits a time delay compensating signal SDCO (2)=Δt to a second signal generating part 12. On the basis of the received time delay compensating signal SDCO (2), the second signal generating part 12 quickens an output timing of a second OFDM signal SSO (2) just for the timeΔt rather than an output timing of a first OFDM signal SSO (1) and creates a transmission signal STX wherein the deviation of multiplex timings in the multiplexing part 13 is compensated.
