Fading Channels - MATLAB & Simulink - MathWorks

The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative to … WebbSlow fading is the variation in the local mean signal level over a wider area. This is mainly caused by obstacles like buildings, trees etc. Between the two, fast fading is easier to deal with, since it is dependent on the movement of the receiver.

To my understanding, shadow fading is due to large obstacles such as buildings, that's the "large-scale". Where does the "small-scale" in multipath fading come from? Obviously, reflection of large buildings can cause multipath. ipotame atelier maths

WebbSlow fading can be caused by events such as shadowing, where a large obstruction such as a hill or large building obscures the main signal path between the transmitter and the receiver. The amplitude change caused by shadowing is often modeled using a log-normal distribution with a standard deviation according to the log-distance path loss model.
