摘　　要：为解决无人机协作通信中的数据时延问题,将复数域网络编码(complex field network coding, CFNC)引入到协作通信中。针对无人机工作时视距与非视距2种典型场景,提出2种适用于无人机网络的部分连通拓扑结构。将CFNC应用到上述无人机网络中,推导基于CFNC的信息传递方案,理论分析结果表明该方案可大幅度提高数据吞吐量性能。最后将CFNC与"RA+BPSK"无人机数据链信号传输体制相结合。基于MATLAB软件的仿真结果表明:CFNC中继方式可以充分获得空间分集增益,相同参数的RA+BPSK+CFNC信号在所提结构中的误符号率明显优于全联通结构。In order to solve the data delay problem in UAV cooperative communication, the Complex Field Network Coding(CFNC) is introduced into cooperative communication. Two partially connective topologies suitable for the UAV network are proposed for two typical scenarios of line-of-sight and non-line-of-sight when the UAV is working.Applying CFNC to the above-mentioned UAV network to derive a CFNC-based information transfer scheme.Theoretical analysis results show that this scheme can improve data throughput performance to a great extent. Finally,the CFNC is combined with the RA+BPSK UAV data link signal transmission system. The simulation results based on MATLAB show that the CFNC relay mode can fully obtain the spatial diversity gain. The error rate of the RA+BPSK+CFNC signal with the same parameters in the proposed structure is significantly better than that of the fully communicated structure.
