PROBLEM TO BE SOLVED: To provide a receiving circuit and a transmitting circuit, and a communication system and a communication method that are excellent in transmission efficiency, and able to use wide-band signals without worrying about interference with other communication.SOLUTION: A receiving circuit of the disclosure includes: a reference signal generating unit that generates a high-frequency reference signal, and transmits the signal to a transmitting circuit side through a signal transmission line that transmits a radio wave while confining it within the transmission line; and a transmission data restoration unit that receives the reference signal that was modulated on the basis of transmission data at a transmission circuit side and returned through the signal transmission line, and restores the transmission data. |
