PURPOSE:To demultiplex original plural signals from a signal in which plural signals of a same frequency subject to amplitude and phase modulation are multiplexed with respect to the multiplexing system and demultiplexing signal in the amplitude and phase modulation. CONSTITUTION:When plural signals of the same frequency subjected to amplitude phase modulation are multiplexed under a prescribed condition, it is noticed that there is 1:1 correlation between the amplitude and phase of the multiplexed signal and the amplitude and phase of the plural original signals. At first, a multiplexer means 4 of a sender side multiplexes plural signals of the same frequency subject to amplitude and phase modulation under a prescribed condition and sends the multiplexed signal. A reception means 1 of a receiver side receives the multiplexed signal and a detection means 2 detects the amplitude and phase of the received multiplexed signal. Then an estimate means 3 estimates the amplitude and phase of the plural signals original to the received multiplexed signal based on the amplitude and phase detected by the detection means 2 and the prescribed condition. |
