摘要 为提升多跳多用户传输系统的频谱效率,本文提出一种基于非正交发送的复数域网络编码协作技术(Complex Field Network Coded Cooperation Based on Non-orthogonal Transmission,CFNCO-NOT)。中继节点对接收数据进行复数域网络编码处理后同时发送,在减小无线信道衰落影响的同时,提高了传输的有效性,并且在目的节点进行简化译码即可实现最佳检测。在两跳的多接入环境中,分析了该技术的频谱效率。结果表明,在高信噪比区域,相对于传统的和基于Alamouti码的数据传输方案,CFNCO-NOT的频谱效率提升了1/3。 Complex field network coded cooperation based on non-orthogonal transmission （CFNCO-NOT） is proposed. Complex field network coding and simultaneous transmission is used to combat wireless fading and improve efficiency of multi-hop multi-user transmission. A simplified detection at destination has the optimal performance. The spectral efficiency is analyzed in two-hop multiple access channels. The results show that at high SNR regimes, the CFNCO-NOT has the higher spectral efficiency compared with the traditional and Alamouti-based strategies.
