Coordinated Direct and Relay Transmission With Linear Non-Regenerative Relay Beamforming [PDF]
IEEE Signal Processing Letters, 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, but also more general traffic scenarios, such as coordinated direct and relay (CDR) transmissions.

A temporal analysis of the swimmers’ coordination in the relay start
Sports Biomechanics, 2021 The main aims of the present research were 1) to characterise the inter-subject and intra-subject timing of the preparatory movements of competitive swimmers during relay starts and 2) to relate the preparatory movements with the relay start outcome. Nine international youth swimmers performed 10 relay freestyle starts (one-step technique) filmed at ...

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 ...
