The **WSSUS** (**Wide-Sense Stationary Uncorrelated Scattering**) **model** provides a [statistical](/source/Statistics) description of the transmission behavior of [wireless](/source/Wireless) [channels](/source/Channel_(communications)). "Wide-sense [stationarity](/source/Stationary_process)" means the [second-order moments](/source/Stationary_process#Weak_or_wide-sense_stationarity) of the channel are stationary, which means that they depend only on the time difference, while "uncorrelated [scattering](/source/Scattering)" refers to the delay τ due to scatterers. Modelling of mobile channels as WSSUS (wide sense stationary uncorrelated scattering) has become popular among specialists. The model was introduced by Phillip A. Bello in 1963.[1]

A commonly used description of time variant channel applies the set of [Bello functions](https://en.wikipedia.org/w/index.php?title=Bello_functions&action=edit&redlink=1) and the theory of stochastic processes.
