Power control — Power control, broadly speaking, is the intelligent selection of transmit power in a communication system to achieve good performance within the system. The notion of good performance can depend on context and may include optimizing metrics such… … Wikipedia
Signal to noise plus interference — (SNIR) is equal to the signal power over the noise power plus interference power.SNIR = Signal Power / (Noise Power + Interference Power) … Wikipedia
Signal reflection — occurs when a signal is transmitted along a transmission medium, such as a copper cable or an optical fiber, some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This… … Wikipedia
Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… … Wikipedia
Signal strength — In telecommunications, particularly in radio, signal strength refers to the magnitude of the electric field at a reference point that is a significant distance from the transmitting antenna. It may also be referred to as received signal level or… … Wikipedia
Power margin — In telecommunication, the power margin is the difference between available signal power and the minimum signal power needed to overcome system losses and still satisfy the minimum input requirements of the receiver for a given performance level.… … Wikipedia
signal-to-noise — noun a) The ratio comparing signal power to noise power. b) The quantity of quality information compared to irrelevant or incorrect information. Syn … Wiktionary
signal-to-noise ratio — The ratio, at a selected point in the circuit, of signal power to noise power. It measures the comprehensibility of a data source or transmission link, usually expressed as the root mean square signal amplitude divided by the root mean square… … Aviation dictionary
Signal level — In a communications system, the signal level is the signal power or intensity at a specified point and with respect to a specified reference level, e.g., 1 mW.It is also the rms signal level of a voltage, e.g., 0.775 VRMS is 0 dBu. From Federal… … Wikipedia
