A Novel Multi-Layer Cooperative Decode and Forward Scheme

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
Decode-and-forward (DF) is one of the most popular approach to transmit information over a cooperative relay channel. In DF, information coming from different sources is simply combined regardless of their respective link qualities, and thus DF is not optimized for any propagation conditions.
