In this paper, we research the performance of a bi-directional three-node cooperative relaying network that aids simultaneous wireless information and power transfer (SWIPT) in a direct connection region that is inuenced by the Nakagami-m fading environment. The information transfer between source nodes can be completed in three equal time phases if we consider two source nodes with direct links and a battery-enabled node.[1] . The maximum-ratio combining (MRC) approach was used at the destination node to use both the direct and relay links. In the rst two stages, the harvested energy at the relay node was used for power splitting (PS), and in the third phase, the harvested energy was used for information processing (IP) and broadcasting. We extract simple and detailed generalized average bit error rate (ABER) expressions for BFSK, BPSK, QPSK, and 4-PAM for the Consider scheme. The derived expressions are applicable to any coherent modulation scheme.
