Pathway Extension of Weibull-Gamma Model

Exact Analysis Of Compound Weibull-Gamma Channel Model

The quality of signal received at the destination depends upon the channel conditions and the propagation environment which can’t be always homogeneous. Weibull which is terrain specific distribution along with Gamma forms a versatile, flexible and multiparameter compound WeibullGamma heterogeneous channel model. Its closed expressions of Probability Density Function (PDF) and Cumulative Distri...

Inverse Flexible Weibull Extension Distribution

In this paper, a new two parameters model is introduced. We called it the inverse flexible Weibull extension (IFW) distribution. Several properties of this distribution have been discussed. The maximum likelihood estimators of the parameters are derived. Two real data sets are analyzed using the new model, which show that the new model fits the data better than some other very well known models.

Weibull-Gamma composite distribution: An alternative multipath/shadowing fading model

Weibull-gamma composite distribution: alternative multipath/shadowing fading model

The Weibull-gamma (WG) distribution, which is appropriate for modelling fading environments when multipath is superimposed on shadowing, is introduced and studied. For this composite distribution the probability density, cumulative distribution, characteristic functions and the moments are derived in closed form. Furthermore, the average bit error and outage probabilities of a receiver operatin...

The Gamma-Exponentiated Weibull Distribution

We study the gamma-exponentiated Weibull distribution which includes as special cases several models such as the exponential, Weibull, exponentiatedWeibull, gamma-exponentiated exponential and exponentiated exponential distributions. This new distribution might be useful for failure time data analysis. We demonstrate that its density function is an infinite linear combination of Weibull densiti...
