Distributions of slow fading

  • Andersen, Jørgen Bach, (Projektdeltager)

Beskrivelse

antprop The classical distributions, Rayleigh and lognormal, are discussed from an interpretation point of view. The lognormal is an excellent practical model for slow fading, but it lacks a theoretical explanation. Instead of the Suzuki distribution (mixture of Rayleigh and log-normal) a new set of distributions are proposed, which is a sum of single and multiple complex Gaussians. H=K+H1+( H2H3+( H4H5H6 Excellent agreement with measurements in urban areas. It is also found that often the local fast fading is not Rayleigh, but has a local Ricean character due to dominant scatterers. [Andersen, Kovacs, 2002]. (J. Bach Andersen)
