WebbSlow &Fast Fading. 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 of the channel to become uncorrelated from its previous value. WebbIf fi is large, the channel is fast-fading (varying). If fi is small, the channel is slow-fading. How large (small) is large (small)?

Slow fading fast fading

Webb23 apr. 2024 · The field strength mid-value of slow fading takes on a logarithmic normal distribution, and is related to location/locale. The fading speed is dependent on the speed of the mobile station. Fast fading: In case the amplitude and phase of the combined wave change sharply with the motion of the mobile station, the change is called “fast fading”. Webbpaths have both slow and fast aspects [1],[2]. The received signal for narrowband excitation is found to exhibit three scales of spatial variation such as Fast Fading, Slow Fading and Range Dependence. Moreover temporal variation and polarization mixing can be present. Fig. 1. Example of multipath due to diffraction effects in a urban environment.
