PROBLEM TO BE SOLVED: To provide a communication system having satisfactory convenience that can automatically select a proper modulation system according to the general tendency, where a user selects the proper modulation system depending on whether an opposite station adopts a stationary type communication system or a mobile type communication system for the communication employing wireless communication. SOLUTION: The communication system can discriminate the stationary type communication system from the mobile type communication system according to a call code. That is, a read section detects the call code, when calling the opposite station and a discrimination section discriminates whether the opposite station discriminates the stationary type communication system or the mobile type communication system depending on the call code, and the discrimination section selects the optimum modulation system from the discrimination result, so as to conduct communication. |
