    Non-orthogonal multiple access (NOMA) can share the same frequency band with multiple mobile devices. In the conventional NOMA scheme, the possible pairs of users are limited and this limitation reduces the amount of capacity improvement. This is because only the receiver in the near user cancels the signal of the other user and then detects the desired signal. In this paper, a joint detection scheme in the far user as well as the near user of the NOMA downlink is proposed. The throughput performance for multiple users with joint detection is evaluated through multi-cell system level simulation. Numerical results obtained through computer simulation show that the proposed scheme increases the system throughput by about 0.1 bit/subcarrier and also improves user fairness.
