Full-Duplex Relay Based on Zero-Forcing Beamforming

Full-Duplex Relay Based on Zero-Forcing Beamforming

In this paper, we propose a full-duplex relay (FDR) based on a zero-forcing beamforming (ZFBF) for a multiuser MIMO relay system. The ZFBF is employed at the base station to suppress both the self-interference of the relay and the multiuser interference at the same time. Numerical results show that the proposed FDR can enhance the sum rate performance as compared to the half-duplex relay (HDR),...

Zero-Forcing Based Self-Interference Cancellation Method for Full-Duplex Relay

Technical Report: Outage Performance of Full-Duplex MIMO DF Relaying using Zero-Forcing Beamforming

In this paper, we deal with the performance analysis of full-duplex relaying in decode-&-forward cooperative networks with multiple-antenna terminals. More specifically, by analyzing the end-to-end statistics, we derive the accurate closed-form expressions of the end-to-end outage probability for both transmit and receive ZFBF scheme over Rayleigh fading environments. Some selected results show...

Virtual full-duplex buffer-aided relaying - Relay selection and beamforming

In this paper, we study virtual full-duplex (FD) buffer-aided relaying to recover the multiplexing loss of halfduplex (HD) relaying in a network with multiple buffer-aided relays, each of which has multiple antennas, through opportunistic relay selection and beamforming. The main idea of virtual FD buffer-aided relaying is that a source and a relay simultaneously transmit their own information ...

Joint Relay-User Beamforming Design in a Full-Duplex Two-Way Relay Channel

A full-duplex two-way relay channel with multiple antennas is considered. For this three-node network, the beamforming design needs to suppress self-interference. While a traditional way is to apply zero-forcing for self-interference mitigation, it may harm the desired signals. In this paper, a design which reserves a fraction of self-interference is proposed by solving a quality-of-service con...
