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...
متن کاملFull-Duplex Two-Way Relay-Interference Channel
A two-way relay-interference channel describes a system of four communicating transceivers with two interjacent parallel relays arranged in a bidirectional 2 × 2 × 2 relayinterference network. Two pairs of transceivers are each communicating bidirectionally with the aid of both relays. All transceivers and relays are assumed to operate in full-duplex mode. Since Interference Neutralization is k...
متن کاملJoint Source and Relay Precoding Design for One-Way Full-Duplex MIMO Relaying Systems
In this paper we address the sum rate maximization problem for a one-way amplify-and-forward relaying system with a full-duplex relay. This optimization problem which requires the joint source and relay precoding design is in general nonconvex. We propose different convex optimization based suboptimal schemes for different system settings. Moreover, we derive a gradient projection based algorit...
متن کاملOn Design of Distributed Beamforming for Two-Way Relay Networks
We consider a two-way relay network, where two source nodes, S1 and S2, exchange information through a cluster of relay nodes. The relay nodes receive the sum signal from S1 and S2 in the first time slot. In the second time slot, each relay node multiplies its received signal by a complex coefficient and retransmits the signal to the two source nodes, which leads to a distributed two-way beamfo...
متن کاملVirtual 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 ...
