| 摘 要： | 为了解决多径干扰对无线定位精度的影响,该文在传统的窄带相关技术的基础上,利用TK算子对其进行改进。改进后的技术在不过多地增加计算负担的情况下,不仅保持了窄带相关技术对于长时延多径信号抑制的功能,而且还改善了其对短时延多径信号抑制效果不佳的缺陷。仿真结果证明,该算法对于无线信道的多径信号抑制起到了一定的改善作用,从而提高了无线定位精度。所以,该研究对于无线定位技术的工程应用和理论研究具有一定的参考价值。

| Abstract: | To solve the accuracy degradation of wireless location that results from multi-path fading, the paper improves the traditional narrow correlation technology using Teager-Kaiser (TK) operator. The improved technology not only retains the merit of narrow correlator, but also mitigates the short-time delay multi-path fading better. The simulation result shows that the technology proposed in this paper can mitigate the multi-path fading better and improve the accuracy of location. |
