Information on Carrier-to-noise Ratio (CNR)

The carrier-to-noise ratio (CNR) is the ratio of the carrier power to the noise power. The carrier-to-noise ratio is a very useful measure in communications because it is not sufficient to simply have a strong signal, since a weak signal in the presence of weak noise may well be as useful as a strong signal in the presence of strong noise.
