Abstract (in Japanese) (See Japanese page) 
(in English) This report presents an indoor event detection using an electric wave.
The proposed event detection exploits an antenna array on the receiver side. Eigenvector spanning signal subspace is obtained with the antenna array and is unique to the propagation environment. The eigenvector spanning signal subspace changes when the indoor environment of interest changes statically or dynamically. In this report, experimental results reveal that the proposed method can distinguish the state when none occurs and that when an event occurs.
