Abstract

Wake-up receivers (WuRxs) allow wireless sensor nodes to run on battery power while maintaining asynchronous, low-latency communication. This paper focuses on WuRxs based on low-frequency pattern matchers (LFPMs). Many recent studies either investigate physical WuRx implementations or simulate WuRx-based protocols. Our goal is to address the challenges that arise when realizing WuRx-based protocols in hardware. These challenges are, that a packet activates unwanted WuRxs, an unreliable address space, and missing cluster broadcast capabilities. The proposed separation sequences and run-length limited patterns ensure a reliable address space. WuRxs based on LFPMs use a fixed pattern matching. Cluster broadcasts are enabled by the proposed variable Manchester coding. Typically, LFPMs use Manchester coding with an efficiency of only 0.5 bit/symbol. We introduce two non-Manchester coding techniques with higher efficiency: lookup table-based coding with an efficiency of 0.71 and 3S2B coding with an efficiency of 0.67.
基于低频模式匹配器的单一可靠寻址唤醒接收器设计模式
唤醒接收器(WuRxs)可让无线传感器节点利用电池供电,同时保持异步、低延迟通信。本文重点讨论基于低频模式匹配器(LFPM)的唤醒接收器。最近的许多研究要么是研究物理 WuRx 实现,要么是模拟基于 WuRx 的协议。我们的目标是解决在硬件中实现基于 WuRx 协议时遇到的挑战。这些挑战包括:数据包会激活不需要的 WuRx、地址空间不可靠以及集群广播功能缺失。所提出的分离序列和运行长度受限模式可确保可靠的地址空间。基于 LFPM 的 WuRx 使用固定模式匹配。建议的可变曼彻斯特编码使群集广播成为可能。通常,LFPM 使用曼彻斯特编码,效率仅为 0.5 位/符号。我们引入了两种效率更高的非曼彻斯特编码技术:基于查找表的编码(效率为 0.71)和 3S2B 编码(效率为 0.67)。

期刊介绍: Launched in 1990, the International Journal of High Speed Electronics and Systems (IJHSES) has served graduate students and those in R&D, managerial and marketing positions by giving state-of-the-art data, and the latest research trends. Its main charter is to promote engineering education by advancing interdisciplinary science between electronics and systems and to explore high speed technology in photonics and electronics. IJHSES, a quarterly journal, continues to feature a broad coverage of topics relating to high speed or high performance devices, circuits and systems.
