摘要

本文将频率异步非正交多址(FA-NOMA)技术应用于低地球轨道卫星通信系统。为了在卫星通信系统中支持大量用户，已经有人尝试使用功率域NOMA (P-NOMA)。然而，P-NOMA在低轨道卫星通信环境中没有好处，因为用户之间的功率差异很小。相比之下，FA-NOMA利用有意的频率偏移而不是环境特性，使其成为在LEO卫星环境中支持大量用户的合适技术。

Frequency Asynchronous Noma In LEO Satellite Communication Systems

In this paper, frequency asynchronous non-orthogonal multiple access (FA-NOMA) is applied to the low earth orbit (LEO) satellite communication (SatCom) system. There have been attempts to employ power domain NOMA (P-NOMA) to support large numbers of users in SatCom systems. However, P-NOMA is not beneficial in LEO SatCom environments where the power difference between users is small. In comparison, FA-NOMA utilizes intentional frequency offsets rather than environmental characteristics, making it a suitable technique for supporting large numbers of users in the LEO satellite environments.
