Group modulation
|
A modulation method used in multiple communication systems that transmit multiple signals simultaneously over the same transmission line. Once modulated, multiple modulated waves with different wave numbers are combined into a single group using frequency division or time division, and then other carrier waves are modulated using this group, hence the name.
