摘　　要：针对存在残留自干扰的全双工双向中继通信系统,分析其差错和中断性能。导出了成对差错概率和中断概率在高发射功率条件下的渐进表达式,给出了系统分集增益与残留自干扰功率特征之间的关系。理论分析和仿真结果表明,相比于半双工双向中继通信系统,自干扰被充分抑制的全双工双向中继通信系统能获得更低的误码率和相近的中断概率。The error and outage performance of a full-duplex two-way relaying communication system was investigated in the presence of residual self-interference. By deriving the asymptotic expression of pairwise error probability and outage probability in the high transmission power region, the relationship between the systematic diversity gain and the power feature of residual self-interference was given out. Theoretical and simulation results show that the full-duplex two-way relaying communication system has better error performance and similar outage probability compared with the half-duplex two-way relaying communication system.
