Abstract

Evolved multimedia broadcast/multicast service (eMBMS) known LTE broadcast as a point to multipoint (PTM) system based on orthogonal multiple access(OMA) technology for live video broadcasting mobile cellular systems. furthermore Non-orthogonal multiple access (NOMA) has been introduced in the next generation of wireless cellular networks. In this article, we propose NOMA-eMBMS model in a symmetric/asymmetric channel. First, introduces a simple NOMA system with Multicast/Unicast for two users that simultaneously operates by a single carrier. LDM-NOMA layered Division Multiplexing splits multistage unicast-multicast power level for two services. Afterwards, Extend to general model for K users with inter service interference. SIC decoder analyses with least complexity form. Finally Matlab simulation shows throughput rates spectral and energy efficiency (SE-EE) NOMA-eMBMS parameters over than OMA-eMBMS technology. Results indicates NOMA-eMBMS combination increases performance than conventional orthogonal multiple access system.

5G网络中多播/单播应用的NOMA-eMBMS蜂窝广播性能

演进的多媒体广播/组播服务(eMBMS)被称为LTE广播，作为一种基于正交多址(OMA)技术的点对多点(PTM)系统，用于实时视频广播移动蜂窝系统。此外，在下一代无线蜂窝网络中引入了非正交多址(NOMA)。在本文中，我们提出了对称/非对称信道中的NOMA-eMBMS模型。首先，介绍了一个简单的多播/单播NOMA系统，该系统通过单个载波同时为两个用户运行。LDM-NOMA分层分组多路复用将多级单播多播功率水平拆分为两种业务。然后，将其推广到具有业务间干扰的K个用户的通用模型。以最小复杂度形式分析SIC解码器。最后，Matlab仿真显示了NOMA-eMBMS技术优于OMA-eMBMS技术的吞吐量、频谱和能量效率(SE-EE)参数。结果表明，NOMA-eMBMS组合比传统的正交多址系统性能有所提高。
