毫米波（mmWave）网络通过提供高速通信支持各种各样的应用，特别是对延迟敏感的应用。毫米波通信中一个公认的挑战是毫米波链路容易受到阻塞，因此，通信可能会中断。在本文中，我们设计和评估了毫米波网络的低复杂性主动传输机制，该机制对此类中断具有弹性。我们的机制建立在多径环境和毫米波网络中链路阻塞概率的精确模型的基础上。我们建议在路径上部署对称的多层码，以在平均信息率和优雅的性能下降之间实现有吸引力的权衡。我们的数值评估表明，与替代方案（如擦除纠错码）相比，我们提出的编码方案确实提供了优雅的性能下降，同时与传统的多层代码设计相比，显著降低了代码复杂性。
Millimeter-wave (mmWave) networks support a large variety of applications, particularly delay-sensitive applications by providing high-speed communication. A well-recognized challenge in mmWave communications is that mmWave links are susceptible to blockage and thus, communication may get disrupted. In this paper, we design and evaluate low-complexity proactive transmission mechanisms for mmWave networks that are resilient to such disruptions. Our mechanisms build on the multipath environment and on the existence of accurate models for link blockage probabilities in mmWave networks. We propose the deployment of symmetric multilevel codes across paths to achieve an attractive trade-off between the average information rate and a graceful performance degradation. Our numerical evaluations show that our proposed coding schemes indeed provide a graceful performance degradation compared to alternative schemes (such as erasure correcting codes), while significantly reducing the code complexity compared to traditional multilevel code designs.
