In this paper, we develop an analytical method in order to derive approximated average symbol error expressions as tractable and closed forms in amplify-and-forward with relay receiving diversity (AFwRRD) and amplify-and-forward with relay transmission diversity (AFwRTD) systems. In AFwRRD system, each relay receives two signals from the source node and the previous relay node and transmits to the next relay or the destination node. In AFwRTD scheme, it is assumed that each relay can receive a signal from the source node or the previous relay node and transmit to the next relay and the destination node. In the proposed analytical method, we modify a dual-hop relay scheme as a single branch channel over Rayleigh fading channels. Furthermore, it is confirmed that the derived performance expressions can be applied to both AFwRRD and AFwRTD schemes. Through a numerical simulation, the analyzed performance well concurs the simulation results and it is confirmed that the performance is well analyzed in terms of the diversity order and the signal to noise ratio (SNR) gain for the different number of relays.
