NOMA的建立及其在5G蜂窝网络中的应用

On the Foundation of NOMA and its Application to 5G Cellular Networks

Hikmet Sari, Ali Maatouk, Ersoy Caliskan, Mohamad Assaad, Mutlu Koca, Guan Gui

摘要:

非正交多址接入(NOMA)被认为是未来5G蜂窝网络中最有前途的技术,在过去几年中已经发表了大量关于该主题的论文。有趣的是,这些作者似乎都没有意识到NOMA的基础实际上可以追溯到2000年,当时一系列论文介绍并研究了使用两组正交信号波形和接收机迭代干扰消除的多址方案。本文的目的是阐明早期文献,并描述基于该概念的实用方案,这对未来5G蜂窝网络中的机器类型通信(MTC)特别有吸引力。使用这种方法,NOMA似乎是正交多址接入的方便扩展,而不是严格的竞争技术,最重要的是,这里不需要使接收机在其他NOMA方案中工作所需的发送用户信号之间的功率不平衡。

英文摘要:

Non-Orthogonal Multiple Access (NOMA) is recognized today as a most promising technology for future 5G cellular networks and a large number of papers have been published on the subject over the past few years. Interestingly, none of these authors seems to be aware that the foundation of NOMA actually dates back to the year 2000, when a series of papers introduced and investigated multiple access schemes using two sets of orthogonal signal waveforms and iterative interference cancellation at the receiver. The purpose of this paper is to shed light on that early literature and to describe a practical scheme based on that concept, which is particularly attractive for Machine-Type Communications (MTC) in future 5G cellular networks. Using this approach, NOMA appears as a convenient extension of orthogonal multiple access rather than a strictly competing technology, and most important of all, the power imbalance between the transmitted user signals that is required to make the receiver work in other NOMA schemes is not required here.
