近年来，随着室内定位技术的不断发展，多种室内定位方法被提出并进行实验。先前的研究提出了一种使用基于接收信号强度指示符（RSSI）的核密度估计（KDE）的统计接入点选择方法。然而，所提出的方法仅通过小区域实验进行测试，其中实验者旁边的人的活动不是很大。本文为了分析该方法在噪声环境下的稳定性，在人体运动较为复杂的日常医疗机构工作场所进行了实验；为了分析该方法的有效性，将其他几种多边定位方法与KDE方法进行了比较。实验结果表明了该方法的有效性和稳定性。
Recently, as the indoor positioning technologies have been developed continuously, several indoor positioning methods have been proposed and experimented. A previous research has proposed a statistical access point selection method using a kernel density estimation (KDE) based on received signal strength indicator (RSSI). However, the proposed method is only test through a small area experiment, where the movement of the people beside the experimenters is not so much. In this paper, to analyze the stability of the proposed method under noisy environment, an experiment in a daily healthcare facility work place, where the human movement is more complex, is designed; to analyze the effectiveness of the method, several others multilateration methods are compared with the KDE method. The experiment results show the effectiveness and stability of the proposed method.
