- White noise refers to a random signal that possesses equal intensity at different frequencies. Continuous time white noise is a wide-sense stationary stochastic process with infinite bandwidth and can be thought of as an idealization of a noisy environment.

Continuous-time white noise. In order to define the notion of "white noise" in the theory of continuous-time signals, one must replace the concept of a "random vector" by a continuous-time random signal; that is, a random process that generates a function of a real-valued parameter .
What engineers like to call a white noise process is a hypothetical beast that is never observed directly in any physical system, but which can be used to account for the fact that the output of a linear time-invariant system whose input is thermal noise is well-modeled by a wide-sense-stationary Gaussian process whose power spectral density is ...
Aug 18, 2023 · In the context of Signal Processing White Noise is usually defined using a single intuitive property: A random process with constant magnitude, for any frequency, of its power spectrum: If $ w \left( t \right) $ is a white noise then its power spectrum is given by $ {S}_{w} \left( f \right) = {\sigma}^{2} $.
Feb 4, 2016 · $\begingroup$ discrete time white noise is any i.i.d. sequence of random variable with finite non-zero variance and $0$ mean. continuous time white noise (when the sampling rate and the variance of the discrete time process tends to $0$) is simpler defined by its primitive : the brownian motion (I prefer Wiener_process). in a same way, the ...

The continuous-time AWGN channel is a random channel whose output is a real random process. Y (t) = X(t) + N(t), where X(t) is the input waveform, regarded as a real random process, and N(t) is a real white Gaussian noise process with single-sided noise power density N0 which is independent of X(t).
