PROBLEM TO BE SOLVED: To provide a receiving device capable of processing multiple signals, in which periods for CDR implementation are provided as preambles, in a narrower time band and without implementing CDR.SOLUTION: A receiving device comprises bandwidth controlling means for determining a transmission start time to notify each transmission device that transmission-side information signals that are transmitted from each of the transmission devices are to be received in a state where they are mutually superimposed, signal differentiating means for generating a pulse signal by differentiating the superimposed transmission-side information signal, signal presence determining means for determining the presence of a pulse signal at a reception start time corresponding to each of the transmission devices, and receiving system selecting means that selects data regenerating means from among the data regenerating means, the signal differentiating means, and the signal presence determining means, while serving as a receiving system to be used in relation to the transmission device in which it is determined that there is a pulse signal. According to the construction, communication of binary logical information from the transmission-side information signal superimposed on a narrower time band becomes possible without implementing CDR. |
