Simulation of Relay Coordination by Labview and the Effect of Relay Coordination on Cost
IOP Conference Series: Materials Science and Engineering, 2019 Abstract In this study, it is emphasized that simulation of the avoidance of unnecessary energy cuts in a sample electricity distribution network. The electricity cut-off costs can be decreased by ensuring that relay coordination end only at the source of the fault from the point of failure.

Beamforming design for coordinated direct and relay systems [PDF]
2012 46th Annual Conference on Information Sciences and Systems (CISS), 2012 Joint processing of multiple communication flows in wireless systems has given rise to a number of novel transmission techniques, notably the two-way relaying based on wireless network coding. Recently, a related set of techniques has emerged, termed coordinated direct and relay (CDR) transmissions, where the constellation of traffic flows is more ...

Optimizing Relay Precoding for Wireless Coordinated Relaying
CoRR, 2014 Processing of multiple communication flows in wireless systems has given rise to a number of novel transmission techniques, notably the two-way relaying based on wireless network coding. Recently, a related set of techniques has emerged, termed coordinated direct and relay (CDR) transmissions, where the constellation of traffic flows is more general ...
