چکیده انگلیسی

Due to ubiquitous access of personal communication services multiple communication through multihops are needed for exchange of data between source and destination across the wireless network. Recently cascade fading models have gained significance as they can model multihop relay fading channels. Generalized Gamma (GG) model being a versatile, flexible and multiparameter model has been selected here as it can generalizes commonly used fading models such as Weibull, Nakagami-m etc. Exact closed expressions of Probability Density Function (PDF) and Cumulative Distribution Function (CDF) are obtained here for the product of multiple GG random variables (RVs). Based on the derived expressions performance analysis of multihop links has been done here in terms of coefficient of variation (CV), amount of fading (AF) and Spectral efficiency and outage probability. Despite of the exact form, the expressions obtained here are in closed form, tractable and easy to evaluate.
