<P>PROBLEM TO BE SOLVED: To provide a communication system and superposition module capable of improving communication speed of communication using a superposition signal. <P>SOLUTION: A superposition module 8 which communicates with another superposition module 8 by using a superposition signal superposed on a transmission signal is provided in each of a transmission unit 1 and a setting device 4. The superposition module 8 transfers setting information for group control or pattern control from the setting device 4 to the transmission unit 1 by the superposition signal. The superposition module 8 conditionally utilizes even a response band as a band capable of superposition for superposing the superposition signal in addition to three bands of the transmission signal of a standby interruption band, a standby band, and a halt band; where the superposition module 8 determines the presence/absence of a response signal during a predetermined detection period after a starting time point of the response band for each frame of the transmission signal by a determination part 85, and utilizes the response band as the band capable of superposition when it is determined that there is no response signal in the response band. <P>COPYRIGHT: (C)2013,JPO&INPIT |
