毫米波（mmWave）网络通过提供高速通信，构成了各种民用和军事应用的核心部分，特别是延迟敏感应用。对于这些应用的前景，一个众所周知的挑战是毫米波链路对阻塞高度敏感，通信可能会中断，特别是在军事通信中。在本文中，我们提出并评估了对网络中断具有弹性的低复杂性主动传输机制。我们的工作利用了多径环境和存在的精确模型来估计毫米波网络中的链路阻塞概率。我们建议跨路径部署多层代码，同时适当地平衡平均信息率和优雅的性能下降。我们定义了速率区域，并使用优化公式为源序列选择一组高性能的速率。我们的评估表明，与其他方案（如擦除纠错码）相比，我们提出的编码方案实现了优雅的性能下降，同时显着降低了代码复杂性。
Millimeter-wave (mmWave) networks form a core part of a variety of civilian and military applications, particularly delay-sensitive applications by offering high-speed communications. For the promise of these applications, a well-known challenge is that mmWave links are highly sensitive to blockage and communication can get disrupted, especially in military communications. In this paper, we propose and evaluate low-complexity proactive transmission mechanisms that are resilient to network disruptions. Our work leverages the multipath environment and the existence of accurate models that estimate the link blockage probabilities in mmWave networks. We propose to deploy multilevel codes across paths while suitably balancing the average information rate with a graceful performance degradation. We define the rate region to operate along with an optimization formulation to select a high-performing set of rates for the source sequences. Our evaluations show that our proposed coding schemes achieve a graceful performance degradation compared to alternative schemes (such as erasure correcting codes), while significantly reducing the code complexity.
