Signal-to-noise ratio is
the difference between the relative strengths of the noise floor power level and the intended signal power level.
Total noise power is a combination of thermal noise and any noise added by the system. Higher signal-to-noise
values are better since there is less of a probability that signal corruption and data errors will occur.
SNRrx = Prx - 10 log ( k Ta B ) { dB } |
where: |
SNRrx = signal-to-noise ratio at detector ( dB ) |
k = Boltzmann's constant = 1.380 · 10-23 ( J/K ) |
Ta = ambient temperature ( K ) |
B = receiver bandwidth at detector ( Hz ) |
