Provided is a communication device which can handle variation in transmission power accompanying switching of a modulation system. Included are: a receiving unit which receives a signal for which modulation according to a modulation system including a first modulation system and a second modulation system is performed based on modulation system designation information by an external transmission device, demodulates the received signal based on modulation system control information, and outputs the received data; a reception level measurement unit which measures a signal level of the signal, and outputs a reception level; an information extracting unit which outputs the modulation system control information based on the received data; a designation information output unit which outputs the modulation system designation information according to a modulation system switching threshold which was set based on a transmission power variation width which is a variation width when transmission power at a time when the signal is transmitted by the transmission device varies before and after switching of the modulation system between the first modulation system and the second modulation system by the transmission device; and a transmission unit which transmits the modulation system designation information to the transmission device.
