| 摘 要： | 为了解决通信频谱利用率的问题,在分析传统译码前向中继协议的基础上,讨论了选择译码前向中继协议(SDF)的中断概率性能和分集增益,并对多种协作模型进行了对比分析,证明了SDF是一种相对较优的协作方式。克服了传统译码前向协议不能提供分集增益的缺点,避免了放大前向协议放大噪声的缺陷。

| Abstract: | In order to solve the problem of communication spectrum efficiency,the paper before analysis of the traditional relay protocol decoding,based on the SDF protocol discussed the outage probability performance and diversity gain,and a variety of collaborative model were compared to prove the SDF is a relatively better ways of collaborating.DF protocol can not overcome the diversity gain provided the shortcomings,and to avoid the noise amplification defects AF protocol. |
