A Fluctuating Line-of-Sight Fading Model With Double-Rayleigh Diffuse Scattering

We introduce the fluctuating double-Rayleigh with line-of-sight (fdRLoS) fading model as a natural generalization of the double-Rayleigh with line-of-sight fading model, on which the constant-amplitude line-of-sight component is now allowed to randomly fluctuate. We discuss the key benefits of the fdRLoS fading model here formulated over the state of the art, and provide an analytical characterization of its chief probability functions. We analyze the effect of the fading parameters that define the model, and discuss their impact on the performance of wireless communication systems.
