与强度无关的位置指纹在线定位改进算法
An Improved Online Position Fingerprint Algorithm for Strength-independent Interference Source Location
摘要
Abstract
The existing hotter indoor location fingerprint positioning system that fixes the transmitter and po-sitions the receiver is applied to the indoor radio interference source location that fixes the receiver and po-sitions the transmitter. And an online locating method considering interference source signal strength is studied in order to overcome the problem that using directly the established fingerprint database with con-stant emission intensity and existing online positioning methods couldn’ t position when interference sources are from different emission intensities. According to the analysis of signal propagation model and the exist-ing online positioning method,the presented method uses the variance of intensity differences to perform po-sitioning calculation. The algorithm basis and procedures are given,and the improved algorithm’ s practica-bility is verified by simulation and experiment. At the same time,the idea of the improved algorithm also has a certain guiding significance to fingerprint positioning systems considering the receiver heterogeneity position.关键词
