本文分析了在功率分配系数固定的情况下，中断概率对非正交多址（NOMA）用户中断容量和期望信源失真的影响。分析表明，在中断概率时，一个强大的用户经历的最大中断容量（和最小的期望失真）是一个弱用户的特征不同。此外，最大化中断容量的中断概率并不能为两个用户提供最小的源失真。对模拟的分析进行了验证。
This Letter analyses the impact of the outage probability on the outage capacity and the expected source distortion of information transmission to non-orthogonal multiple access (NOMA) users with a fixed set of power allocation coefficients. The analysis shows that the outage probability at which a strong user experiences the maximum outage capacity (and the minimum expected distortion) is characteristically different from that of a weak user. Moreover, the outage probability that maximises the outage capacity does not provide the minimum source distortion for both users. The analysis is validated against simulation.
