Synonym: carrier
| Wikipedia: Carrier wave |
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.[1] This carrier wave is usually of much higher frequency than the input signal.
Frequency modulation (FM) and amplitude modulation (AM) are commonly used methods to modulate the carrier. In the case of single-sideband modulation (SSB) the carrier is suppressed (and in some forms of SSB eliminated). The carrier must be reintroduced at the receiver by a beat frequency oscillator (BFO).
The frequency for a given radio or television station is actually the carrier wave's center frequency.

Newer forms of radio communication, such as spread spectrum and ultra-wideband, do not transmit a conventional carrier wave, nor does OFDM, which is used in DSL and in the European standard for HDTV.
In telecommunication, the term carrier (cxr) or carrier wave has the following meanings:
