Non-orthogonal multiple access (NOMA) makes multiple mobile users share the same frequency band. In a conventional NOMA scheme, the possible pairs of users are limited and this limitation reduces the amount of capacity improvement. This is because only a receiver in a near user cancels the signal of the other user and then detects the desired signal. In this paper, a joint detection scheme is applied to a far user as well as a near user in a NOMA downlink. In the proposed scheme, the joint detection in the far user increases the possibility of forming user pairs owing to proportional fair scheduling. The throughput performance for multiple users with joint detection is evaluated 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. |
