Exact Analysis Of Compound Weibull-Gamma Channel Model

[Full Text]



Amandeep Kaur, Jyoteesh Malhotra



KEYWORDS: Weibull-gamma; mellintransformation; heterogeneousmodel; fading channel; Amount of fading; Coefficient of variation.



ABSTRACT: 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 multiparametercompound Weibull-Gamma heterogeneous channel model.Its closed expressions of Probability Density Function (PDF) and Cumulative Distribution Function (CDF) are obtained here. Based on these derived expressions , exact and closed formexpressions of various important performance metrics such as Coefficient of Variation (CV), Amount of fading (AF) outage probability and spectral efficiency are also evaluated.The derivedexpressions aretractable and are easy to evaluate using standard software tools such as MATLAB.
