carrier wave

n. electromagnetic wave that can be modulated to transmit a signal from the transmitter to the receiver

In telecommunications, a carrier wave, or carrier is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information, for example voice or data, to be transmitted. This carrier wave is usually of much higher frequency than the baseband modulating signal (the signal which contains the information).
