论文摘要
在这封信中，我们研究了一个两用户的下行链路异步非正交多访问（ANOMA），反馈有限。我们采用了最大分配分配的最高标准，并得出了最大速率上限和下限的闭合形式表达式。证明与NOMA相比，疾病可以达到相同甚至更高的平均最大速率，反馈率较低。此外，我们提出了一种适用于Noma和Anoma的量化量化算法。模拟结果表明，与常规统一量化器相比，优化的量化器显着提高了平均最大速率，尤其是在反馈率较低的情况下。
In this letter, we study a two-user downlink asynchronous non-orthogonal multiple access (ANOMA) with limited feedback. We employ the max-min criterion for the power allocation and derive the closed-form expressions for the upper and lower bounds of the max-min rate. It is demonstrated that ANOMA can achieve the same or even higher average maxmin rate with a lower feedback rate compared with NOMA. Moreover, we propose a quantizer optimization algorithm which applies to both NOMA and ANOMA. Simulation results show that the optimized quantizer significantly improves the average max-min rate compared with the conventional uniform quantizer, especially in the scenario with a low feedback rate.
