carrier-to-receiver noise density (C/kT)

In satellite communications, the ratio of the received carrier power to the receiver noise power density. Note 1: The carrier-to-receiver noise density ratio is usually expressed in dB. Note 2: The carrier-to-receiver noise density is given by C/kT, where C is the received carrier power in watts, k is Boltzmann’s constant in joules per kelvin, and T is the receiver system noise temperature in kelvins. Note 3: The receiver noise power density, kT, is the receiver noise power per hertz.
