It is straightforward to analyze the channel capacity for the arbitrary number of users in non-orthogonal multiple access (NOMA), due to the simple mathematical expression based on the ideal Gaussian modulation. However, under the practical modulation, such as binary phase shift keying (BPSK), it is not straightforward to analyze the performance for the entire range of the power allocation factor. Even with such difficulties, the performance has been analyzed for NOMA with two users, recently. In this paper, we challenge the performance analysis for NOMA with three users. It is shown for the entire coordinates of the power allocation factor pair that the performance of NOMA degrades with respect to that of orthogonal multiple access (OMA), such as time division multiple access (TDMA) and frequency division multiple access (FDMA). With such performance degradation, we triple the system capacity, because three users are served on the same channel resources. Therefore, a trade-off between the performance and the system capacity could be considered in NOMA.
