First-Order Intensity Statistics for Non-Rayleigh Fading

Abstract

This report examines first-order intensity statistics under multipath scintillation conditions which are not sufficiently severe to lead to fully developed Rayleigh fading. It is shown that neither Rice nor Nakagami-m statistics are accurate in general. Actual signal intensity statistics can be systematically characterized in terms of the refractive index spatial power spectrum and the signal Fresnel length. Numerous calculated results are provided for signal intensity distributions and channel symbols bit error rates in non- Rayleigh fading. Keywords: Scintillation effects, Propagation effects, Satellite communications, Satellite links, Ionospheric scattering.
