A communication device receives a signal from a device of a communicating party and identifies each party device. An inherent pattern frequency spectrum is set to each party device. The communication device includes a memory means for storing information to identify the party device and a correspondence to the frequency spectrum set in the party device, an acquiring means for acquiring a frequency spectrum included in a receiving signal, a specifying means for comparing the frequency spectrum acquired by the acquiring means with the frequency spectrum stored in the memory means to specify a party device in which the frequency spectrum acquired by the acquiring means corresponds to the frequency spectrum stored by the memory means. |
