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.

A novel fading model for channels with multiple dominant specular components
- 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.
