论文摘要
为了克服连续干扰取消（SIC）的实用问题，本文提出了针对下链路大量多输入多输入多数输出（MIMO）网络的双极速率分解多访问速率的多元访问（RSMA）技术。通过对极化干扰的效果进行建模，进行了深入的理论分析，其中我们为中断概率和千古概率得出了紧密的封闭形式近似值。仿真结果验证了理论分析的准确性，并确认了所提出方法的有效性。例如，在低至中度的横切干扰下，我们的结果表明，所提出的双偏光MIMO-RSMA策略的表现优于单极化的MIMO-RSMA对应物，对于所有考虑的残留SIC误差水平。
Aiming at overcoming practical issues of successive interference cancellation (SIC), this paper proposes a dual-polarized rate-splitting multiple access (RSMA) technique for a downlink massive multiple-input multiple-output (MIMO) network. By modeling the effects of polarization interference, an in-depth theoretical analysis is carried out, in which we derive tight closed-form approximations for the outage probabilities and ergodic sum-rates. Simulation results validate the accuracy of the theoretical analysis and confirm the effectiveness of the proposed approach. For instance, under low to moderate cross-polar interference, our results show that the proposed dual-polarized MIMO-RSMA strategy outperforms the single-polarized MIMO-RSMA counterpart for all considered levels of residual SIC error.
