Abstract
In this paper, a full-duplex orthogonal frequency division multiplexing (OFDM) millimeter wave systems with correlated estimation errors and partially-connected structures is investigated to improve the spectral efficiency and energy efficiency. To attenuate the self-interference caused by full-duplex mode, a zero-space projection based method is proposed. Then, a two-stage hybrid beamforming scheme is developed. In the fist stage, the correlated channel estimation errors are considered to design the robust fully digital beamformers. In the second stage, an alternating algorithm with closed-form solutions is proposed to solve the hybrid processors. The numerical results show that the proposed scheme has superior performance over existing designs.
