摘要

混合非正交多址（NOMA）的关键思想是允许用户使用在基于正交多址（OMA）的传统网络中无法访问的带宽资源，同时保证其与传统网络的兼容性。然而，在传统的混合NOMA下行网络中，一些用户可以访问比其他用户更多的带宽资源，从而导致潜在的性能损失。那么，如果用户可以访问相同数量的带宽资源呢？这封信的重点是一个简单的双用户场景，并开发了分析和仿真结果，以揭示在这种考虑的场景中，传统的混合NOMA仍然是一种最佳的传输策略。

A Study on the Optimality of Downlink Hybrid NOMA

The key idea of hybrid non-orthogonal multiple access (NOMA) is to allow users to use the bandwidth resources to which they cannot have access in orthogonal multiple access (OMA) based legacy networks while still guaranteeing its compatibility with the legacy network. However, in a conventional hybrid NOMA downlink network, some users have access to more bandwidth resources than others, which leads to a potential performance loss. So what if the users can access the same amount of bandwidth resources? This letter focuses on a simple two-user scenario, and develops analytical and simulation results to reveal that for this considered scenario, conventional hybrid NOMA is still an optimal transmission strategy.

期刊介绍： The IEEE Signal Processing Letters is a monthly, archival publication designed to provide rapid dissemination of original, cutting-edge ideas and timely, significant contributions in signal, image, speech, language and audio processing. Papers published in the Letters can be presented within one year of their appearance in signal processing conferences such as ICASSP, GlobalSIP and ICIP, and also in several workshop organized by the Signal Processing Society.
