"WebFlat fading and frequency-selective fading are considered as small-scale fading. Time dispersion due to multipath causes the transmitted signal to undergo either flat fading or frequency-selective fading, where the small delay spread gives rise to flat fading and the large delay spread brings about frequency-selective fading.
