Outage-Based Resource Allocation for DF Two-Way Relay Networks with Energy Harvesting

Abstract: A joint resource allocation algorithm to minimize the system outage probability is proposed for a decode-and-forward (DF) two-way relay network with simultaneous wireless information and power transfer (SWIPT) under a total power constraint. In this network, the two sources nodes exchange information with the help of a passive relay, which is assumed to help the two source nodes’ communication without consuming its own energy by exploiting an energy-harvesting protocol, the power splitting (PS) protocol.

“…Over the past few decades, the two-way relay network (TWRN) [1][2][3][4][5][6][7][8][9][10][11][12][13] has aroused great interest due to the overwhelming development of wireless cellular systems, especially when one-way relaying is of low spectral efficiency because of the half-duplex constraint. In a TWRN system, two source nodes exchange information through a relay node.…”

“…In the three-stage scheme, source nodes send their corresponding messages to the relay in the first two stages, respectively. In the third stage, the relay processes received signals with either a decode-and-forward (DF) approach [1][2][3][4][5][6] or an amplify-and-forward approach [7][8][9][10][11][12][13], and then broadcasts back to the source nodes. In [14], Xu et al proposed a multiply-and-forward (MF) approach, in which the relay multiplies the signals sent from different source nodes.…”

“…Thereby, this is a suitable candidate for SWIPT, where we can use the excessive power used by the pilot signal for EH [ 37 ]. The power allocation and optimization comprise one of the important resource management features in SWIPT, which improves spectral efficiency and overall system performance, as mentioned in recent articles [ 38 , 39 , 40 , 41 ]. In this case study, we study the optimum power ratio between pilot and information symbols.…”
