Multi-relays Selection Scheme in Cooperative Networks Based on Decode-and-Forward Protocol
Yi Li · Communications technology · 2010
The cooperative communication technology could protect the anti-fading channel,and provide diversity gain,and thus has become the research focus.In order to avoid the low resource efficiency of all-participated cooperations in decode-and-forward cooperative communication networks,a new relays selection scheme based on channel capacity gain is proposed.The simulation results indicate that the proposed scheme with half-number relays selection could achieve same performance as the conventional schemes with optimal relays selection.
