What is the variance of white Gaussian noise?
White noise has infinite power; therefore, samples of a white noise process would require infinite variance. Alternatively, white noise has infinite bandwidth, so the Nyquist rate for recovering white noise from its samples would be infinite.
How do you calculate the variance of a noise signal?
The noise variance is calculated as the mean of the difference between these two frames, the corresponding signal value is calculated as the mean over all the signal values in these frames. The graph in Figure 1 (a) shows the variance plotted over the respective mean signal value.
What is the power of AWGN?
AWGN Power
I oc is defined in C. S0033 as the power spectral density of a band-limited white noise source (simulating interference from other cells) as measured at the access terminal antenna connector. If you have accounted for path loss, then AWGN power is equivalent to I oc .
What is noise variation?
A Noise Variation is a permit that allows a deviation from the prescribed standards of the NPCR, but also limits the level of sounds that can be emitted.
