can anyone tell me how to calculate noise variance σ²/2, if the noise power spectral density is set to -162dBm/Hz. Noise component is additive white circularly symmetric gaussian complex noise. How noise variance is related to noise power spectral density?
eqn holds, if you convert left side to simple ratio from dBm. you'll have to find out whats the relevant BW, it is not mentioned in the first post. You could also assume the BW of the noise is the same as that for your signal, but it really depends on the system.
