摘要 为了优化协作通信系统的性能,提出了一种基于改进的DAF-DF混合模式的自适应中继选择算法。首先,中继节点根据目的接收端能否正确解码源发送端发送的数据决定是否参与中继转发;接着,基于各个中继节点的链路状态选出最优中继参与协作传输;最后,根据最优中继能否正确译码,确定协作方式是译码放大转发还是译码转发协作方式。仿真结果表明,相比于增量中继算法,该算法可以改善系统的误码性能,提高正确接收的比特数目,且在必要时再进行协作通信,不仅提高传输速率,还因节省系统资源而提高频谱利用率,能更好的改善系统性能。 In order to optimize the performance of cooperative communication system, an adaptive relay se- lection algorithm based on the improved DAF-DF hybrid mode is proposed. Firstly, the relay determines whether or not to forward the information to the destination according to whether or not the destination could correctly decode the information from the source, then the best relay is selected to participate in forwarding data in accordance with the state information of channels, and finally the best relay chooses amplify-and- forward or decode-and-forward mode in accordance with that whether or not it could decode the informa- tion correctly. Simulation results show that this modified DAF-DF hybrid algorithm could improve the error -bit performance, raise the transmission rate and save the resources of the system. The modified DAF-DF hybrid algorithm could fairly improve the performance of the communication system.
