WebMoreover, small-scale fading based on Doppler spread can either be fast or slow fading. In fast fading, the Doppler spread time is high, and the coherence time is less than the symbol duration while channel variations are faster than baseband signal variations, The opposite situation results in slow fading (Sklar, 1997). Web• Fast fading (small-scale fading) • Slow fading (large-scale fading) 7. Compare fast fading and slow fading.

David83 said: Fast vs. slow is in the time domain, whereas flat vs. selective is in the frequency domain. 1- If the channel changes withing a symbol time it is fast. Otherwise it is not fast. 2- If the channel frequency response is constant over the signal bandwidth then it is flat. Otherwise, it is frequency selective. mario + rabbids kingdom battle ben switch

Depending on how rapidly the transmitted baseband signal changes as compared to the rate of change of the channel, a channel may be classified either as a fast fading or slow fading channel. i) Fast fading

Web(2) Shadow fading is called large-scale fading; on the contrary, fading caused by multipath is called small-scale fading. 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.
