Abstract
In this paper, we propose various kinds of two-way multi-antenna relaying with simultaneous wireless information and power transfer (SWIPT) and investigate their performance. Specifically, we first consider a two-way relay network where two single-antenna end nodes communicate with each other through a multi-antenna relay node that is energy constrained. This relay node harvests energy from the two end nodes and use the harvested energy for forwarding their information. Six relaying schemes that support the considered network then build on the power splitting-based relaying and time switching-based relaying protocols. The average bit error rates of these schemes are evaluated and compared by computer simulations considering several network parameters, including the number of relay antennas, power splitting ratio, and energy harvesting time. Such evaluation and comparison provide useful insights into the performance of SWIPT-based two-way multi-antenna relaying.
Highlights
Simultaneous wireless information and power transfer (SWIPT) has gained great interest due to its capability to deal with the energy scarcity in energy-constrained wireless networks [1,2,3,4,5,6,7,8,9,10].In the seminal works [1,2], the fundamental trade-off between information and power transfer in different point-to-point wireless channels was studied
We evaluate the performance of the proposed multiple-antenna relaying schemes (i.e., power splitting (PS)-data contents by forward (DF), PS-DF-STC, PS-AF, time switching (TS)-DF, TS-DF-STC, and TS-AF) in terms of average bit error rates (BERs) of the end nodes T1 and T2
We can see that the theoretical results perfectly match their simulation counterparts, which verifies the BER formulae derived in Sections 3.1 and 3.2

The at relevant sum‐rate this paper multiple will investigate the average bit error rates is used in the PS-DF-STC and TS-DF-STC schemes with the aim of achieving a better end-to-end (BERs) of the proposed relaying schemes as a function of the number of relay antennas, power decoding performance.
