System performance analysis of cooperative multihop relaying network applying approximation to dual-hoprelaying network

摘要

In this paper, the closed-form expressions for outage probability, channel capacity, and average symbol error probability are derived for amplify-and-forward multihop relay network. Based on approximation of multihop relay by dual-hop relay systems, the analytical expressions are obtained for the case when maximal ratio combining technique is employed at each relay while destination node uses selection combining technique. The impact of system and channel parameters on the system performances is investigated, and numerical results are graphically presented. The derived analytical expressions are verified by numerical simulation.
