Amount of Fading Analysis For Composite Fading Channel using Holtzman approximation

In this paper we present amount of fading for composite fading channel. For this purpose two probability density functions have been taken. One is Weibull function and another one is log-normal function. Both functions have been combined to find the new composite fading channel called as WeibulULog-Normal fading channel. Further to find amount of fading first we need equation in simplest form of composite fading channel which is really a tedious work to find. So Holtzman calculation method has been considered to find the equation in simplest form of composite fading channel. The achieved simplest-form equation is precise for undesirable light shadowed fading as well as multipath fading channels which further enable to develop the amount of fading parameter. Finally amount of fading has been derived from obtained WeibulULog-Normal composite function. Further probability density function and Cumulative distribution function of simplest form equation have been plotted and analysed. At the end amount of fading parameter for composite Weibull/Log-Normal function has been plotted and analysed.
