中文摘要：
在并行中继网络中,基于复数域网络编码的并行中继方案具有较大的传输时延以及目的节点检测复杂度,提出了一种复数域网络编码的优化设计方案。性能分析和仿真结果表明,优化设计方案具有与并行中继方案相同的网络吞吐量和分集增益性能,且该方案进一步减少了信源符号的传输时延,降低了目的节点检测复杂度,与并行中继方案相比,符号错误概率有所降低。
英文摘要：
Considering that in networks with parallel relays,complex field network coding-based parallel relay scheme（CFNC-PR） has larger transmission delay and detection complexity of destination,an optimization design scheme for complex field network coding is proposed.Performance analysis and simulation results show that,on the premise that network throughput and diversity gain are not lost,the scheme remarkably decreases the transmission delay of source symbols,reduces the detection complexity of destination.Compared with CFNC-PR,the symbol error probability of the scheme is reduced at a certain extent.
