Carrier multiplex communication

Japanese: 搬送多重通信 - はんそうたじゅうつうしん（英語表記）carrier multiplex communication

A multiplex communication method in which voice is modulated with different carrier waves to obtain single sidebands, which are then arranged on the frequency axis so that they do not overlap with each other and transmitted along the transmission path. When receiving, the reverse operation is performed to demodulate the voice. This makes it possible for multiple simultaneous communications to be made over a single transmission path. Due to the difficulty of making filters, etc., a method of bundling multiple communication paths and increasing the degree of multiplexing through group modulation is used.

音声をそれぞれ異なる搬送波で変調し，その単側波帯を得，それらを互いに重複しないように，周波数軸上に配列して伝送路に伝送する多重通信方式をいう。受信に際しては，この逆操作を行って音声に復調する。これによって，1本の伝送路で多数の同時通信が可能となる。複数個の通話路を束とし，群変調によって多重度を上げる方法がフィルターの難易性などから行われている。多重通信【辻井重男】
