说明：  可以实现室内定位跟踪，采集采样点的RSS为指纹库，计算观测点的RSS与指纹库匹配，从而确定观测点的位置，选取的采样点比较少，可以实现简单的定位。
(Indoor location and tracking can be achieved. The RSS of the sampling point is taken as the fingerprint library, and the matching between RSS and fingerprint Library of the observation points is calculated. Thus, the location of observation points is determined, and the selected sampling points are relatively few, so that a simple location can be achieved.)
