A short description of “Signal Fading Statistics”
- The rapid variations (fast fading) in signal power caused by local multipaths are represented by Rayleigh distribution.
- The long-term variations in the mean level are denoted by lognormal distribution.
- With a LOS propagation path, the Rician distribution is often used for fast fading.
- Thus, the fading characteristics of a mobile radio signal are described by the following statistical distributions:
– Rayleigh Distribution
– Rician Distribution
– Lognormal Distribution
