Abstract


  • In this paper, the performance of in-band fullduplex OFDM relaying systems with energy-harvesting and selfinterference cancellation in the polarization domain is analyzed.

    Specifically, we use the time switching-based relaying protocol

    to implement energy harvesting. The harvested energy is used

    by the relay to forward the transmitted information from the

    source. To cancel the self-interference, the polarization-enabled

    digital self-interference cancellation scheme is deployed at the

    relay. Our simulation results show that the full-duplex OFDM

    energy harvesting relaying system almost doubles the throughput,

    while maintaining the same bit error performance by a modest

    increase in the signal-to-noise ratio compared to the half-duplex

    OFDM energy harvesting relaying system. It is also revealed

    that the optimal time splitting factor should be less than 0.3 to

    maximize the full-duplex system throughput.
