In particular we divide the models into three classes by separating the received signal in three scale of spatial variation such as fast fading, slow fading (shadowing) and path loss. Moreover, several models for small scale fading are considered such as Rayleigh, Ricean, Nakagami and Weibull list of monin organic syrups

"WebWhen the bandwidth is too small for the signal to resolve the individual components, the frequency response is approximately flat because of the minimal time dispersion caused by the multipath channel. This kind of multipath fading is often referred to as narrowband fading, or frequency-flat fading. " - Small scale rayleigh fading
