K distribution: an appropriate substitute for Rayleigh­lognormal
distribution in fading­shadowing wireless channels

Indexing terms: Rayleigh­lognormal distribution, K distribution, fading, shadowing,
wireless channel
Rayleigh­lognormal distribution, proven useful for modeling fading­shadowing wireless
channels, has a complicated integral form. In this paper we have accurately approximated it
by the K distribution. This distribution is simpler and thus more appropriate for analysis and
design of wireless communication systems.
Introduction: Rayleigh­lognormal distribution is a mixture of Rayleigh and lognormal
distributions [1]:
