Everything about Gaussian Noise totally explained
Gaussian noise is
noise that has a
probability density function (abbreviated pdf) of the
normal distribution (also known as Gaussian distribution). In other words, the values that the noise can take on are Gaussian distributed.It is most commonly used as additive
white noise to yield
additive white Gaussian noise (AWGN).
Explanation
Gaussian noise is properly defined as noise with a Gaussian amplitude distribution. This says nothing of the
correlation of the noise in time or of the
spectral density of the noise. Labeling Gaussian noise as 'white' describes the correlation of the noise.
It is necessary to use the term "white Gaussian noise" to be correct. Gaussian noise is sometimes misunderstood to be white Gaussian noise, but this isn't the case.
