Summary: | Orbital angular momentum (OAM) with index modulation (IM) (OAM-IM) is a recently proposed line-of-sight wireless communications technique that has been attracting recent attention. OAM-IM utilizes the indices of activated OAM mode combinations to convey additional information per transmission interval. Full-duplex relaying (FDR) may be employed to improve communication range, spectral efficiency or error performance in wireless communication systems. In the interest of improving the error performance of OAM-IM while allowing extended communication range, in this paper, we present three variant FDR schemes for single-active mode orbital angular momentum index modulation (FDR-SA-OAM-IM). A transmission mechanism for the proposed schemes is formulated for the link between the source and relay nodes (Link 1) and between the relay and destination nodes (Link 2). Scheme 1 employs OAM mode division multiplexing (OAM-MDM) for Link 1 and Link 2. Scheme 2 employs single-active OAM-IM (SA-OAM-IM) for both Link 1 and Link 2. Scheme 3 employs SA-OAM-IM for Link 1 and OAM-MDM for Link 2. The average bit error probability of the proposed schemes is affirmed by the Monte Carlo simulations, and we reveal that the FDR mechanism displays a generally enhanced error performance. |
