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).
Carrier waves are used when transmitting radio signals to a radio receiver.
The frequency for a given radio station is actually the carrier wave's center frequency.
Newer forms of radio communication, such as spread spectrum and ultra wide band, do not transmit a conventional carrier wave, nor does COFDM, which is used in
In telecommunication, the term carrier (cxr) or carrier wave has the following meanings:
