Multicarrier division duplex aided millimeter wave communications
The existing Time Division Duplex (TDD) and Frequency Division Duplex (FDD) techniques rely on a guard time and/or guard band to avoid Self-Interference (SI) between the uplink and downlink channels, which results in the wastage of precious spectral resources. The Full-Duplex (FD) schemes of In-Band Full Duplex (IBFD) as well as Multicarrier Division Duplex (MDD) may overcome this drawback while retaining the key benefits of both TDD and FDD. Moreover, the MDD exhibits the exclusive benefits of the reduced Peak-to-Average Power Ratio (PAPR) for signal transmission as well as the SI-free signal detection. Against this background, in this work, we propose a novel FD scheme conceived for frequency-selective millimeter Wave (mmWave) channels, which have not been investigated in the open literature. Furthermore, we propose a novel Projection aided Iterative Eigenvalue Decomposition (P-IEVD) algorithm, which performs nullspace SI cancellation in the inherent beamforming structure of mmWave communication. Our simulation results confirm that the MDD is capable of outperforming its Half-Duplex (HD) counterparts of TDD/FDD, even the IBFD can only achieve a better bandwidth efficiency than the MDD when a sufficiently high SNR is provided.

Abstract
The existing Time Division Duplex (TDD) and Frequency Division Duplex (FDD) techniques rely on a guard time and/or guard band to avoid Self-Interference (SI) between the uplink and downlink channels, which results in the wastage of precious spectral resources. The Full-Duplex (FD) schemes of In-Band Full Duplex (IBFD) as well as Multicarrier Division Duplex (MDD) may overcome this drawback while retaining the key benefits of both TDD and FDD. Moreover, the MDD exhibits the exclusive benefits of the reduced Peak-to-Average Power Ratio (PAPR) for signal transmission as well as the SI-free signal detection. Against this background, in this work, we propose a novel FD scheme conceived for frequency-selective millimeter Wave (mmWave) channels, which have not been investigated in the open literature. Furthermore, we propose a novel Projection aided Iterative Eigenvalue Decomposition (P-IEVD) algorithm, which performs nullspace SI cancellation in the inherent beamforming structure of mmWave communication. Our simulation results confirm that the MDD is capable of outperforming its Half-Duplex (HD) counterparts of TDD/FDD, even the IBFD can only achieve a better bandwidth efficiency than the MDD when a sufficiently high SNR is provided.
