Web4.3 Small Scale Fading. We’ve seen in § 3.3 the impact of multiple rays on propagation models: this effect of multipath causes deep fades within small distances and is referred to as small-scale fading. Another important yet different cause of fading is that of small frequency variations such as Doppler effect. Both of these small-scale fading effects are … WebFading channel manifestations can be broadly divided into two categories: large-scale fading and small-scale fading. Large–scale fading represents the average signal power attenuation or path loss due to multipath signal propagation over large areas.
