摘要 针对多源多中继协作网络模型,提出一种公平的节点选择与用户调度方案。出于优化平均信道质量的思想,每个传输时隙,选择信道条件差异最大的两个用户同时进行传输信息。中继节点选择基于PF比例公平调度算法,能保证中继节点处的负载均衡。然后在中继端采用一种网络编码传输方案。最后,与其他2种调度方案相比较仿真系统的误码率性能。 A fair node selection and user scheduling scheme is proposed for multi-source and multi-relay cooperative network. To optimize the average channel quality, two users that differ greatly in channel conditions are chosen to transmit information simultaneously in every transmit slot. Relay node selection based proportional fairness scheduling algorithm can be realized the load balance among the relays. And a kind of network coding transmission scheme is adopted in relay terminal. Ultimately,compared with two other scheduling algorithms, the BER performance of the system is simulated.
