“…The authors in [11] jointly optimize the modulation order and transmitting precoder for a multiuser system, where the objective is to minimize the average SER subject to the QoS requirement on total required data rate. In [12], a two-user non-orthogonal multiple access (NOMA) system is considered, where the modulation orders are determined by minimizing the maximum SNR to satisfy the QoS requirement based on block error rates of the users. In [13], an optimization problem is proposed for a free space optical communication system to maximize the average throughput by selecting the largest modulation order under the constraint on transmit power and the QoS for a given bit error rate.…”

In multiuser communication systems, it is required to support high data rate applications with guaranteed quality of service~(QoS) which is generally characterized by the channel capacity or target data rate. It is desirable to characterize the QoS requirement by both the target data rate and error tolerance for each user. Given the QoS requirements, the optimal resource allocations for the power and bandwidth are related to the modulation orders for the transmitted symbols. In this paper, various optimization problems are formulated to maximum the number of users or to minimize the power/bandwidth/montary cost, subject to different constrains on user priorities and QoS requirements. The modulation order aware solutions are obtained for each user by solving constrained integer optimization problems.
