carrier signal — A signal of chosen frequency generated to carry data; often used for long distance transmissions. A carrier signal does not convey any information until the data is added to the signal by modulation and then decoded on the receiving end by… … Dictionary of networking
Carrier recovery — A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal s carrier wave and the receiver s local oscillator for the purpose of coherent demodulation. Example of QPSK… … Wikipedia
Carrier-to-noise ratio — In telecommunications, the carrier to noise ratio, often written CNR or C/N , is the signal to noise ratio (SNR) of a modulated signal. The CNR is the quotient between the average received modulated carrier power C and the average received noise… … Wikipedia
carrier — An analog signal of fixed amplitude and frequency that is combined with a data carrying signal to produce an output signal suitable for transmitting data. See also carrier signal … Dictionary of networking
carrier detect — detection of a carrier signal, detection of a communications tone … English contemporary dictionary
Carrier interferometry — (CI) is a type of spread spectrum multiple access typically employed with Orthogonal frequency division multiplexing (OFDM). CI spreading codes are commonly used to spread data symbols across multiple OFDM subcarriers for diversity benefits and… … Wikipedia
Carrier sense multiple access with collision detection — (CSMA/CD), in computer networking, is a network control protocol in which *a carrier sensing scheme is used. *a transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam… … Wikipedia

Carrier-Suppressed Return-to-Zero (CSRZ) — is an optical signal format. In CSRZ the field intensity drops to zero between consecutive bits (RZ), and the field phase alternates by π between neighbouring bits, so that if the phase of the signal is e.g. 0 in even bits (bit number 2 n ), the… … Wikipedia
Carrier current — is a method of low power AM broadcasting that does not require a broadcast license in the United States, but is allowed on the campus of any school, so long as the normal FCC Part 15 Rules are adhered to when measured at the edge of the campus.… … Wikipedia
