论文摘要
在本文中，我们研究了具有不完美的连续干扰取消（SIC）的多细胞上行非正交多访问（NOMA）系统。公式优化问题的目的是最大程度地减少用户服务质量约束下的总功耗。被考虑的问题首先转化为线性编程问题，提出了集中和分布的最佳解决方案。提出了数值结果，以验证提出的解决方案的性能，并评估不完美的SIC对系统性能的影响。
In this paper, we investigate a multi-cell uplink non-orthogonal multiple access (NOMA) system with imperfect successive interference cancellation (SIC). The objective of the formulated optimization problem is to minimize the total power consumption under users' quality-of-service constraints. The considered problem is first transformed into a linear programming problem, upon which centralized and distributed optimal solutions are proposed. Numerical results are presented to verify the performance of the proposed solutions and evaluate the impact of imperfect SIC on the system performance.
