WebThere are four types of small-scale fading. They are flat fading, frequency-selective fading, fast fading and slow fading. Small-scale fading, depending on multipath time delay spread, can be flat fading and frequency-selective. In flat fading the bandwidth (BW) of the signal is less than the coherence bandwidth of the channel.
