PROBLEM TO BE SOLVED: To perform phase compensation so that phase characteristics between sub modulation signals continue when the sub modulation signals are composed in a receiver side in response to an embodiment in which the sub modulation signals are transmitted through a plurality of different transmission paths.SOLUTION: The receiving device distributes, arranges and transmits a plurality of sub modulation signals, generated by dividing an occupied band of transmission signals, on a frequency axis, extracts the plurality of sub modulation signals from the received signals and restores each sub modulation signal to the original band for composition and demodulation thereof, where the plurality of sub modulation signals are transmitted on a plurality of transmission paths, which comprises: phase compensation means in the transmission path that detects a phase difference of a superposing area where the sub modulation signals, transmitted on the same transmission path of the plurality of transmission paths and adjacent to each other, superpose on the frequency axis and compensates the phase difference between the adjacent sub modulation signals; and phase compensation means between the transmission paths that detects a phase difference of a superposing area where the sub modulation signals, transmitted on different transmission paths of the plurality of transmission paths and adjacent to each other, superpose on the frequency axis and compensates the phase difference between the sub modulation signals transmitted on the different transmission paths. |
