Question

Which distribution describes the shadowing effect?

(a) Log normal distribution

(b) Nakagami distribution

(c) Cauchy distribution

(d) Rayleigh distribution

This question was posed to me by my school principal while I was bunking the class.

This is a very interesting question from Practical Link Budget Design Using Path Loss Models topic in section Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Right option is (a) Log normal distribution

For explanation I would say: Log normal distribution describes the random shadowing effects. It occurs over a large number of measurement locations which have the same T-R separation, but have different clutter on the propagation path.
