摘要

超宽带（UWB）技术是低延迟高分辨率定位的理想选择。为了提高超宽带定位系统的定位精度，提出了x律运算方法。该方案显著降低了低信噪比采样的贡献，提高了脉冲的时间分辨率。因此，XLO实现了到达时间（ToA）定位精度，而现有方法需要更多的能量和带宽才能实现。用于定位的XLO显著的性能增益使XLO成为同时定位和通信的良好候选者，具有低复杂性，高性能和低功耗，适合物联网（IoT）设备。

X-law operation for energy-efficient time-of-arrival positioning to achieve higher accuracy with lower bandwidth: A game-changer for UWB localization devices

Ultra-wideband (UWB) technology is a good candidate for low-latency high-resolution localization. This paper proposes the

x

-law operation (XLO) to boost the positioning accuracy of UWB localization systems. The proposed scheme significantly reduces the contribution of low-SNR samples and increases the time resolution of the pulse. Thus, the XLO achieves a time-of-arrival (ToA) positioning accuracy that existing methods require more energy and bandwidth to attain. The significant performance gain of the XLO for localization makes the XLO a good candidate for simultaneous positioning and communication with low complexity, high performance, and low power consumption suited for Internet of Things (IoT) devices.
