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 /k T , 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, k T , is the receiver noise power per hertz . ( 188 )
