利用自适应门限直接分量检测提高WCDMA/FDD网络定位精度
Improve Positioning Accuracy in WCDMA/FDD Networks Utilizing Adaptive Threshold for Direct Component Detection
摘要：
在非视距传播条件下，直流分量的功率会被显著衰减。因此，直接分量的检测加重，这会降低到达时间移动定位的精度。本文的目标是确定可能性，以改善估计的直接分量的时间延迟，通过降低检测阈值。对三种不同的阈值计算方法进行了测试，并对定位误差进行了比较。
英文摘要：
In NLOS propagation conditions power of direct component can be attenuated significantly. Therefore detection of direct component is aggravated which can degrades accuracy of Time of Arrival mobile positioning. The goal of this paper is to determine possibilities to improve estimation of direct component time delay by reducing detection threshold. Three different methods for calculating threshold has been tested and compared in terms of positioning error.
