WebJan 26, 2024 · Mainly there are two main types of propagating models: large-scale and small-scale fading propagating models. Large-scale fading is due to the shadowing caused by the obstacles present in the channel. In contrast, small-scale fading replicates the fast evolutions of the receiving signal over short distances or short periods. Webroughly divided into two types (Figure 2.1): • Large-scale fading, due to path loss of signal as a function of distance and shadowing by large objects such as buildings and hills.
