Abstract


  • In this paper, throughput and bit error performance of an in-band full duplex (IBFD) relaying system assisted by the radio frequency energy harvesting technique and the polarization-enabled digital self-interference cancellation (PDC) scheme are investigated. In particular, the relay node harvests power from the wireless radio frequency signal transmitted from the source node and uses this power to amplify and forward signals to the destination. Meanwhile, the PDC scheme is used at the relay node to cancel the self-interference signal in order to facilitate the concurrent in-band transmission and reception. The impact of both energy harvesting and self-interference cancellation on the throughput and the error performance of the system is evaluated. Our simulation results show that the full-duplex energy harvesting relaying system almost doubles the system throughput, compared to the half-duplex energy harvesting relaying system, at the cost of about 5 dB inferior error performance, partially because of the noise effect of the PDC scheme. We also show that to achieve a high throughput along with a good error performance in the full-duplex energy harvesting relaying system, a combined selection of a high signal-to-noise ratio and a suitable energy harvesting time is required.
