The document presents a new fading model for wireless channels that have multiple dominant specular components. It derives novel transformations that unify existing non-central chi, generalized Ricean and κ-μ fading models. The new closed-form fading distribution model is flexible and simple, representing multiple specular and diffuse scatter components with a parameter to adjust the severity of fading. All parameters have clear physical meanings.

1. A NovelFading Modelfor ChannelsWith Multiple Dominant Specular
Components
Abstract:
Achieving maximum spectral efficiency in future femtocell and high-speed
train applications requires better channel models for wireless channels
having multiple dominant specular components. Novel transformations
that unify the non-central chi, generalized Ricean and κ - μ fading models
are derived. A new fading distribution model is given in closed-form. The
fading model is flexible and simple representing multiple specular and
diffuse scatter components, with a parameter allowing for adjustment of
the severity of the fading. All parameters have clear and usefull physical
meaning. The new model is related to the Ricean model as the Nakagami-
m model is related to the Rayleigh model; the new model is related to the
Nakagami-m model as the Ricean model is related to the Rayleigh model.
