Duplex Schemes in Multiple Antenna Two-Hop Relaying
2008
EURASIP Journal on Advances in Signal Processing
Preserved Fulltext
A novel scheme for two-hop relaying defined as space division duplex (SDD) relaying is proposed. ...
In SDD relaying, multiple antenna beamforming techniques are applied at the intermediate relay station (RS) in order to separate downlink and uplink signals of a bi-directional two-hop communication between ...
However, [16] [17] [18] [19] only assume one-way relaying schemes for the multiple antenna RSs. In [20] , multiple antennas and CSI at the RS are applied in the context of DF two-way relaying. ...

With half-duplex relay nodes, the end-to-end delay performance of a multihop network degrades as the number of hops increases, because the relay nodes cannot receive and transmit at the same time. ...
