NO CARRIER (capitalized) is a text message transmitted from a modem to its attached device (typically a computer ), indicating the modem is not (or no longer) connected to a remote system. NO CARRIER is a response message that is defined in the Hayes command set. Due to the popularity of Hayes modems during the heyday of dial-up connectivity ...
Six-position, six-contact (6P6C) jack, which could be wired as RJ11, RJ14, or RJ25. A registered jack ( RJ) is a standardized telecommunication network interface for connecting voice and data equipment to a computer service provided by a local exchange carrier or long distance carrier. Registered interfaces were first defined in the Universal ...

Double-sideband suppressed-carrier transmission. Double-sideband suppressed-carrier transmission ( DSB-SC) is transmission in which frequencies produced by amplitude modulation (AM) are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed.

Software for error-correcting codes. Simulating the behaviour of error-correcting codes (ECCs) in software is a common practice to design, validate and improve ECCs. The upcoming wireless 5G standard raises a new range of applications for the software ECCs: the Cloud Radio Access Networks (C-RAN) in a Software-defined radio (SDR) context. The ...
Carrier-sense multiple access ( CSMA) is a medium access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus or a band of the electromagnetic spectrum . Under CSMA, a transmitter uses a carrier-sense mechanism to determine whether another ...
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 . In the transmitter of a communications carrier system, a carrier wave is modulated by a baseband signal.
