本文研究了接收比特信息率（RBIR）技术在IEEE 802.11ac/ax系统中的应用，以估计在系统级仿真中用于抽象物理层（PHY）性能的有效信噪比。基于802.11ac物理层在标准平坦衰落和独立相同的分布和空间相关频率选择单用户和多用户多输入多输出信道上运行的仿真结果，对RBIR技术进行了评估。我们得出的结论是，RBIR物理层抽象方法足够精确，可以在降低计算复杂性的情况下提供关于系统级性能和设计选项的一阶见解。最后，介绍了RBIR物理层抽象方案在飞行调度调制码方案中的应用，以达到目标服务质量。
This paper investigates the application in IEEE 802.11ac/ax systems of received bit information rate (RBIR) technique in order to estimate the effective signal-to-interference-plus-noise ratio used to abstract the physical layer (PHY) performance in system level simulations. The RBIR technique is evaluated based on simulation results of 802.11ac PHY operating over both canonical flat fading and independent and identical distributed and spatial-correlated frequency selective single-user and multi-user multiple input multiple output channels. We have concluded that RBIR PHY abstraction methodology is accurate enough to provide first order insights on system level performance and design options with reduced computational complexity. Finally, it is also described the application of RBIR PHY abstraction scheme to schedule on the flight the modulation code scheme that achieve a target quality-of-service.
