A cooperative non-orthogonal multiple access (CNOMA) system and an orbital angular momentum (OAM) -based multiple-input multiple-output multiplexing system is proposed as full-duplex relaying (referred to as CNOMF) by the cell center user to the cell edge user in this letter. The proposed CNOMF scheme can significantly improve the capacity of cell edge user and sum channel capacity via user-assisted decode and forward based full-duplex relaying by utilizing different ranges of OAM modes for a 6G (Sixth generation) wireless communication system, compared to other existing schemes (For example, CNOMA-MIMO with FDR, and orthogonal multiple access with OAM-MIMO and half duplex relaying); this was demonstrated via numerical result analysis.

基于协同 NOMA-OAM-MIMO 的 6G 全双工中继容量分析

提出了一种协作非正交多址(CNOMA)系统和基于轨道角动量(OAM)的多输入多输出复用系统作为小区中心用户到小区的全双工中继(简称CNOMF)边缘用户在这封信中。与其他方案相比,所提出的 CNOMF 方案可以通过为 6G(第六代)无线通信系统利用不同范围的 OAM 模式,通过用户辅助解码和基于前向的全双工中继显着提高小区边缘用户的容量和总信道容量。现有方案(例如,带有 FDR 的 CNOMA-MIMO,以及带有 OAM-MIMO 和半双工中继的正交多址接入);这是通过数值结果分析证明的。
