Carrier-to-receiver noise density

Carrier-to-receiver noise density ( C /k T ): 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.
