摘要
本文介绍了一种用于超宽带(UWB)车载网络的前导码仲裁规则和干扰抑制(PARIS)方法。汽车技术的进步使人们越来越依赖线束,导致成本上升、电子集成难题和不利的环境影响。为了解决这些问题,我们探索使用 UWB 无线网络,其特点是传输功率低、信号穿透能力强。在汽车环境中实施 UWB 的一个重大挑战是 UWB 干扰导致的帧误码率(FER)增加。我们的实验表明,配备相同 UWB 网络的车辆在紧密定位时,FER 约为 6%。对于通信可靠性至关重要的汽车应用来说,这种水平的 FER 是个问题。为了缓解这一问题,我们开发了一种具有抗干扰能力的 PARIS 通信算法。正如本研究中所确定的,PARIS 利用了 UWB 的两个关键特性。首先,它优先考虑信号接收时间而不是无线电信号功率,通过在所需帧到达前的最佳时机启动接收器来增强干扰抑制能力,从而最大限度地减少数据丢失。其次,该算法利用了同时接收的帧中前导码的层次性,通过根据前导码层次对来自关键通信设备的帧进行优先级排序,将数据丢失率降低到 10^{-5}$ 的数量级。在无线车载网络中实施基于 UWB 的 PARIS 方法,可将线束重量减轻约 20%,为应对传统布线系统带来的挑战提供了一个前景广阔的解决方案。
Preamble Arbitration Rule and Interference Suppression-Based Polling Medium Access Control for In-Vehicle Ultra-Wideband Networks
This paper introduces a preamble arbitration rule and interference suppression (PARIS) method for ultra-wideband (UWB) in-vehicle networks. Advancements in the automotive technology have led to increased reliance on wire harnesses, resulting in higher costs, electronic integration challenges, and adverse environmental effects. To address these problems, we explored the use of UWB wireless networks, which are characterized by low transmission power and superior signal penetration capabilities. A significant challenge associated with implementing UWB in automotive environments is the increased frame error rate (FER) caused by UWB interference. Our experiments indicate that vehicles equipped with identical UWB networks exhibit an FER of approximately 6% when positioned closely. This level of FER is problematic for automotive applications, where reliable communication is paramount. To mitigate this problem, we developed an PARIS communication algorithm that is robust against interference. As identified in this study, PARIS leverages two key characteristics of UWB. First, it prioritizes the timing of signal reception over radio signal power, enhancing interference suppression by activating the receiver at the optimal moment before the desired frame arrives, thereby minimizing data loss. Second, the algorithm exploits the hierarchical nature of preamble codes in simultaneously received frames, reducing data loss rate to the order of
$10^{-5}$
by prioritizing frames from critical communication devices based on the preamble code hierarchy. Implementing the UWB-based PARIS method in wireless vehicle networks can reduce the weight of the wire harnesses by approximately 20%, offering a promising solution to the challenges posed by traditional wiring systems.
