On the performance of SWIPT-enabled two-way AF relay networks in [formula omitted] fading.

In this study, we examine the performance of simultaneous wireless information and power transfer (SWIPT)-enabled two-way amplify-and-forward relay networks operating over κ − μ distributed channels. We adopt a three-node wireless communication system in which two source nodes communicate with one another in half-duplex mode through a battery-enabled relay node. In order to facilitate simultaneous energy harvesting through the radio-frequency signals and information transmission activities at the relay node, we use a time switching (TS) technique. At the destination nodes, the selection-combining technique is applied to utilize the two intended signals received through both direct and relay links. We obtain analytical expressions for the cumulative distribution function (CDF) and moment-generating function (MGF) in the system under study. We derive expressions for the outage probability (OP) and average symbol error rate (ASER) for a general-order coherent rectangular quadrature amplitude modulation scheme using the derived CDF expression. Additionally, we investigate the ASER for non-coherent modulation schemes using the derived MGF expression. The system's diversity order is examined by employing the asymptotic OP. We also emphasize the impact of the TS factor, energy conversion efficiency, and fading characteristics on the investigated network. To validate the analytical expressions, we perform Monte-Carlo simulations. [ABSTRACT FROM AUTHOR]
