Full-Duplex Relaying with Half-Duplex Relays
We consider “virtual” full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multi-hop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage. With such a pipelined scheme, the source ...
متن کاملAntenna Selection in Full-Duplex Cooperative NOMA Systems
We investigate the problem of antenna selection (AS) in full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay assists transmission from a multi-antenna base station (BS) to a far user, while at the same, the BS transmits to a near user. Specifically, based on the end-to-end signal-to-interferenceplus-noise ratio at the near and far users, two...
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 ...
متن کاملA New Hybrid Half-Duplex/Full-Duplex Relaying System with Antenna Diversity
The hybrid half-duplex/full-duplex (HD/FD) relaying scheme is an effective paradigm to overcome the negative effects of the self-interference incurred by the full-duplex (FD) mode. However, traditional hybrid HD/FD scheme does not consider the diversity gain incurred by the multiple antennas of the FD node when the system works in the HD mode, leading to the waste of the system resources. In th...
متن کاملRecent Advances in Full-Duplex Relaying
This presentation provides an overview of essential aspects to be considered when introducing full-duplex operation into relaying systems. Firstly, the unavoidable self-interference is mitigated by passive isolation, active cancellation and beamforming-based suppression as well as transmit power adaptation. Secondly, the feasibility of full-duplex operation in the presence of residual self-inte...
