本文介绍了基于我们提出的阵列传感器的活动识别。阵列传感器由接收端的天线阵列组成,并将接收到的信号分解为特征向量和特征值。它利用这些组件取决于其应用程序,如活动识别。当事件发生时,传播环境发生变化,因此特征向量和特征值发生变化。特征向量和相应的特征值是其传播环境所固有的,因此也是其活动所固有的。根据这些成分的变化,我们可以准确地检测活动。此外,使用基于这些组件的机器学习,所提出的阵列传感器可以对几种更复杂的状态和活动进行分类。本文还介绍了阵列传感器的各种应用。
This paper introduces activity recognition based on our proposed array sensor. The array sensor consists of an antenna array on the receiver side and decomposes received signals into eigenvectors and eigenvalues. It exploits these compo- nents depending on its applications, such as activity recognition. When an event occurs, the propagation environment changes, and thus the eigenvector and eigenvalue change. Eigenvector and corresponding eigenvalue are inherent to their propagation environments so that to activity as well. Based on the change of these components, we can detect an activity accurately. In addition, using machine learning based on these components, the proposed array sensor can classify several more complex states and activities. This paper also introduces various applications of array sensor.
