What is log normal shadowing?
The log-normal distribution describes the random shadowing effects which occur over a large number of measurement locations which have the same T-R separation, but have different levels of clutter on the propagation path. This phenomenon is referred to as log -normal shadowing.
What is the difference between log distance path loss model and log normal shadowing?
Log distance path loss model
The model encompasses random shadowing effects due to signal blockage by hills, trees, buildings etc. It is also referred as log normal shadowing model. for a large cell.
What is log normal fading?
Log-Normal Fading (Shadowing)
Experimentally it has been found that the path loss in cluttered multipath environments is log-normally distributed. This means that the log of the path loss (for example, the path loss expressed in dB) has a nor- mal distribution.
What is shadowing effect in wireless communication?
Shadowing effects are defined as the effects of received signal power fluctuations due to obstruction between the transmitter and receiver. Therefore, the signal changes as a result of the shadowing mainly come from reflection and scattering during transmittal.
