Satellite and Space Engineering - Problem #7
This is part of a series of problems looking at topics in satellite and space communications and systems engineering.
Determine the thermal (Gaussian) noise power (dBW) in a radio receiver (in this case we are thinking of a satellite receiver, but the approach is generic to all radio receivers).
You are given the bandwidth of the receiver (in Hz) and the receiving system noise temperature (in Kelvin).
You should take Boltzmann's constant to be 1.380649×10^−23 J/K.
Hint: See https://en.wikipedia.org/wiki/Noise_figure#General - but don't forget to convert to dB!
Example: The thermal noise power in a satellite receiver with a bandwidth of 2 MHz and a receiving system noise temperature of 200 K is around -142.6 dB.
Some future problems in this series will build on work done in previous problems, so if you get a working solution I suggest you hang onto the code!
