摘要

IEEE 802.11b无线局域网被广泛用于实现基于Wi-Fi的TDoA (Time Difference of Arrival)室内定位。提出了一种新型的IEEE 802.11b基带接收机及其定位系统。帧检测器和相位恢复块用于帧接收和频偏补偿。贝克码重相关器是专门为提高抗噪声性能而设计的。实验结果表明，该系统达到了亚米级的距离定位精度。

Design of IEEE 802.11b baseband receiver for indoor localization

IEEE 802.11b WLAN is widely used to implement Wi-Fi based Time Difference of Arrival (TDoA) indoor localization. This paper presents a novel IEEE 802.11b baseband receiver and the corresponding localization system. Frame detector and phase recovery block are dedicated to frame reception and frequency offset compensation. Baker code re-correlator is specially designed to improve anti-noise performance. Experimental results demonstrate that the proposed system achieves sub-meter range localization precision.
