协作通信技术能够保护信道的抗衰落性，并提供分集增益，因此成为研究的热点，为了避免解码转发协作通信网络中所有参与者协作时资源利用率低的问题，提出了一种新的基于信道容量增益的中继选择方案，仿真结果表明，所提出的中继选择方案具有较好的性能，中继数目的选择可以达到与传统的最优中继选择方案相同的性能。
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.
