Abstract

This letter presents an IEEE 802.15.4a/4z compliant IR-UWB transceiver for high-precision ranging. By virtue of the proposed digital deserialization–serialization, the TX can generate the intersymbol-interference (ISI)-free IEEE 802.15.4a/4z packet. The proposed analog finite impulse response (FIR)-based TX pre-emphasis improves

$3.5\times $

time-of-arrival (ToA) measurement precision without substantial power overhead and fulfills the spectrum requirement of the standard and the worldwide UWB regulations. The presented transceiver consumes 8.7 mW in TX mode and 21 mW in RX mode.

符合 IEEE 802.15.4a/4z 标准的 6-9-GHz 低功耗红外无线收发器，具有脉冲预加重功能，可实现高 ToA 精度

本文介绍了一种用于高精度测距的符合 IEEE 802.15.4a/4z 标准的 IR-UWB 收发器。通过所提出的数字解串-序列化，发射机可以生成无符号间干扰（ISI）的 IEEE 802.15.4a/4z 数据包。所提出的基于模拟有限脉冲响应（FIR）的发射机预加重技术可提高到达时间（ToA）测量精度 3.5 倍，而无需大量的功率开销，并能满足标准和全球 UWB 法规的频谱要求。该收发器在发送模式下的功耗为 8.7 mW，在接收模式下的功耗为 21 mW。
