Finite series representation of Rician shadowed channel with integral fading parameter and the associated exact performance analysis

With the deployment of small cells and device to device communications in future heterogeneous networks, in many situations we would encounter mobile radio channels with partly blocked line of sight component, which are well modeled by the Rician shadowed (RS) fading channel. In this paper, by the usage of Kummer transformation, a simplified representation of the RS fading channel with integral fading parameter is given. It is a finite series representation involving only exponential function and low order polynomials. This allows engineers not only the closed-form expressions for exact performance analysis over RS fading channel, but also the insights on the system design tactics.
