论文摘要
工业互联网的发展（IoT）要求提高频谱效率（SE）。比Nyquist（FTN）和非正交多访问（NOMA）更快，都是有望改善SE的范式，而无需任何额外的光谱资源。 FTN和NOMA的结合是一个有趣的问题，最近重点关注。在NOMA技术中，用户配对和功率分配是确定系统容量的关键算法。本文首先提出了基于FTN的单载波（SC）NOMA系统的联合用户配对和功率分配算法。然后，研究了基于FTN的多输入 - 多数输出（MIMO）NOMA，并提出了动态的用户配对和功率分配方案。在这两种情况下，最大可用的总率（ASR）是目标。虽然基于公平原则，但用户在NOMA系统中的SE保证不少于OMA系统中的SE。仿真结果表明，基于FTN的Noma具有ASR和服务质量（QOS）性能的优势。据我们所知，本文是基于FTN的NOMA中用户配对和功率分配问题的第一个解决方案，这证明了这两种最新技术的结合具有很大的优势。
The development of the industrial Internet of Things (IoT) calls for higher spectrum efficiency (SE). Faster than Nyquist (FTN) and non-orthogonal multiple access (NOMA) are both promising paradigms to improve the SE without any extra spectrum resources required. The combination of FTN and NOMA is an interesting issue and has been focused on recently. In the NOMA technology, user pairing and power allocation are key algorithms determining system capacity. This paper first proposes a joint user pairing and power allocation algorithm for the FTN-based single-carrier (SC) NOMA system. Then, the FTN-based multiple-input-multiple-output (MIMO) NOMA is studied and a dynamic user pairing and power allocation scheme is presented. In both scenarios, the maximum available sum rate (ASR) is the target. While based on the fairness principle, the user's SE in the NOMA system is guaranteed to be no less than that in the OMA system. Simulation results show the advantage of the FTN-based NOMA with the proposed scheme in ASR and quality of service (QoS) performance. As far as we know, this paper is the first solution to the issue of user pairing and power allocation in FTN-based NOMA, which proves the great advantage of the combination of these two state-of-the-art technologies.
