This paper studies a FD cooperative non-orthogonal multiple access (NOMA) system in terms of pairwise error probability (PEP) while considering imperfect successive interference cancellation (ipSIC). Exact closed-form expressions of the PEP performance for the system users are derived. The PEP expressions are derived under both ideal condition and in the presence of self-interference due to the FD relaying. Moreover, we derive asymptotic PEP expressions to evaluate an effective diversity order for the considered system. Through the derived (asymptotic) expressions and simulation results, we demonstrate that self-interference due to FD relaying has a great influence on the performance of the full-duplex relay.

本文在考虑不完美连续干扰消除 (ipSIC) 的同时，在成对错误概率 (PEP) 方面研究了 FD 协作非正交多址 (NOMA) 系统。推导出系统用户的 PEP 性能的精确闭式表达式。PEP 表达式是在理想条件下和由于 FD 中继而存在自干扰的情况下导出的。此外，我们推导出渐近 PEP 表达式来评估所考虑系统的有效多样性顺序。通过导出的（渐近）表达式和仿真结果，我们证明了 FD 中继引起的自干扰对全双工中继的性能有很大影响。
