Abstract

This paper presents and evaluates the performance of wireless networks that utilize the decode-and-forward relay. This multi-hop relaying scheme communicates over Extended Generalized- $${\mathcal {K}}$$ K ( $$\hbox {EG}{\mathcal {K}}$$ EG K ) composite fading channels to create performance evaluation. To this effect, new exact and easy to compute formulas for several performance metrics are derived. More specifically, new and exact-form mathematical formulas are derived for the cumulative distribution function, the generalized moments of the overall end-to-end signal-to-noise ratio, the outage probability ( $${\hbox {P}}_{\text{out}}$$ P out ), the ergodic capacity ( $${\mathcal {C}}_{\text{Ergodic}}$$ C Ergodic ), the moment generating function, and the average error probability ( $${\hbox {Pr(e)}}$$ Pr(e) ) for different modulation schemes. Moreover, we carried out a series of computer simulation experiments in order to testify the accuracy of the derived framework. Finally, we discussed the impact of different parameters including fading/shadowing parameters, transmitted power and the number of hops on the derived expressions.
