摘要
本文研究了瑞利衰落信道中相位/正交相位不平衡(IQI)影响下的NOMA系统的性能。具体而言，推导了底层NOMA场景的封闭形式的pair - wise error probability (PEP)表达式，并利用该表达式分析了IQI下NOMA用户可实现的多样性顺序。蒙特卡罗仿真结果证实了相应的分析，并说明了IQI对NOMA用户性能的不利影响。
Pairwise Error Probability of Non-Orthogonal Multiple Access with I/Q Imbalance
In this paper, we investigate the performance of a NOMA system under the effect of in-phase/quadrature-phase imbalance (IQI) over Rayleigh fading channels. Specifically, a closed-form pairwise error probability (PEP) expression for the underlying NOMA scenario is derived, which is subsequently utilized to analyze the achievable diversity order of NOMA users under IQI. Monte Carlo simulation results are provided to corroborate the corresponding analysis and to illustrate the detrimental effect of IQI on the performance of NOMA users.
