This is mainly caused by obstacles like buildings, trees etc. Between the two, fast fading is easier to … WebbIn slow fading channels, the coherence time of the channel is long and encoding can be performed only over a single or a few fading states (e.g., time diversity). While encoding still averages out the randomness of the noise, it may not be possible to fully average out the randomness of the channel. inboy
