基于信道状态信息子载波特征差分的 人体移动检测方法
Human Movement Detection Method Based on Subcarrier Characteristic Difference with Channel State Information
摘要
Abstract
Wireless signal can be easily affected by multipath effects and small scale fading in the room,which makes the existing human movement detection methods based on radio frequency signals can not guarantee the robustness and reliability of the slow movement behavior recognition. This paper finds that different subcarriers have sensitive difference to human behavior by analyzing the correlation between human behavior and CSI subcarrier. Then the channel state information subcarrier characteristic difference algorithm based on the discrete wavelet transform is pro?posed,and the device-free human movement detection is designed. The experimental results show that the average de?tection accuracy of this method can reach 93%in two kinds of indoor scenes with rich and sparse multipath.关键词
