摘要

摘要本文提出了采用非正交多址接入和解码前向半双工中继协议的双跳合作网络有效容量（EC）的分析结果。假设无线传播以 Nakagami-m 分布为模型，我们推导出了新的有效容量分析结果。这些分析结果进一步扩展到以混合伽马分布为模型的广义衰落信道。我们提出的分析方法得到了数值结果和蒙特卡罗模拟的验证。此外，数值评估结果表明了各种系统级参数对所考虑系统性能的影响，包括衰落、功率分配系数和延迟约束的影响。

Effective capacity of cooperative relaying systems with non-orthogonal multiple access

Abstract

In this paper, we present analytical results on the effective capacity (EC) for a dual-hop cooperative network employing non-orthogonal multiple access and the decode-and-forward half-duplex relaying protocol. Assuming that wireless propagation is modelled by the Nakagami-m distribution, novel analytical results for the EC are deduced. These analytical results are further extended to the generalized fading channels, modeled by a mixture gamma distribution. Our proposed analysis is validated by numerical results and Monte-Carlo simulations. Besides, the numerically evaluated results have demonstrated the impact of various system-level parameters on the performance of the considered system, including the impact of fading, the power allocation coefficient and the delay constraints.
