由于具有支持大规模连接和高频谱效率的潜力，NOMA是未来无线接入网(FRA)的有力候选。然而，NOMA最大的缺点是由于用户间的干扰，在实现连续干扰抵消(SIC)时会产生误差。本文推导了Nakagami-m衰落信道中存在SIC错误时下行链路(NOMA)误码率的闭式精确表达式。通过计算机仿真验证了推导公式的正确性。结果表明，m参数仍然像OMA系统一样代表分集顺序。另外，NOMA的用户误码率性能在很大程度上取决于功率分配系数。

英文摘要：
NOMA is as a strong candidate for the Future Radio Access Network (FRA) due to its potential to support massive connectivity and high spectral efficiency. However, the most important drawback of NOMA is the error during Successive Interference Canceller (SIC) is implemented because of the inter-user interferences. In this paper, we derive closed-form exact Bit-Error Rate expressions for Downlink(DL) NOMA over Nakagami-m fading channels in the presence of SIC errors. The derived expressions are validated by the computer simulations. It is shown that the m parameter still represents the diversity order like as OMA systems. Besides, the BER performances of users for NOMA have substantially depended on the power allocation coefficient.
