What is Carrier-to-Noise Density Ratio (C/N0)? Carrier-to-noise density ratio (C/N0) is the ratio of carrier power to noise power density and denotes the strength of the power of carrier wave relative to the noise. C/N0 is often used in calculating link budget, and it describes the clarity of signal. Thus, the receiver should keep the … Continue reading Carrier-to-Noise Density Ratio (C/N0) Explained
