摘要

随着传感器技术的普及，研究人员通过观察住宅中信号传输的变化，从WiFi中提取出反映家庭成员活动的信道状态信息（CSI）。然而，在住宅中，WiFi信号仍然受到多径效应的影响。因此，我们基于三元闭包构造了相邻尺度间的多尺度CSI组合掩模矩阵。接下来，我们提出了一个基于聚合亲和传播算法的竞争定位网络。实验表明，在室内环境下，与其他经典算法相比，该算法取得了显著的改进。

Muloc: Multi-scale combination mask indoor localization network for WiFi based on channel state information

With the popularization of sensor technology, researchers extract Channel State Information (CSI) from WiFi, which reflects the movement of family members by observing changes in signal transmission in residences. However, WiFi signals are still affected by multipath effects in residences. Therefore, we construct a multi-scale CSI combination mask matrix between adjacent scales based on the ternary closure. Next, we propose a competitive localization network based on aggregated affinity propagation algorithm. Experiments have been conducted to demonstrate that the proposed algorithm achieves significant improvement compared to other classical algorithms in the indoor environment.
