摘要

Wi-Fi信道状态信息（channel state information，CSI）的人体活动识别（human activity recognition，HAR）方法在动作监测等领域被广泛应用，但仍面临部署成本高和感知范围有限等挑战。为解决这些问题，提出了一种移动通信网长期演进的注意力卷积神经网络（long term evolution attention-guided ConvNeXt ，LTE-ACN），利用移动信号进行活动识别。首先，基于小区参考信号提取信道状态信息有效特征；其次，进行噪声滤波、Savitzky-Golay平滑、峰谷增强和格拉姆角场变换等信号处理来构建动作数据集；最后，将增强后的图像数据输入LTE-ACN模型，通过改进的ConvNeXt架构有效地降低了特征信息损失，同时引入卷积块注意力模块（convolutional block attention module，CBAM）提升关键特征的表达能力，强化了空间域内的特征关联性。实验结果表明，所提方法的6类动作识别平均准确率达到了96.44%，验证了基于LTE信号进行人体动作识别的可行性。

Abstract

Wi-Fi channel state information (CSI)-driven human activity recognition (HAR) has been widely studied for applications in activity monitoring. However

challenges such as high deployment costs and limited sensing range remain. To address these

long term evolution attention-guided ConvNeXt (LTE-ACN) was proposed

which used mobile communication LTE signals for activity recognition. Firstly

effective features of channel state information were extracted based on cell reference signals. Then

signal processing methods including noise filtering

Savitzky-Golay smoothing

peak-valley enhancement

and Gramian angular field transformation were applied to construct the motion dataset. Finally

the enhanced image data was input into the LTE-ACN model

in which the improved ConvNeXt architecture effectively reduced the feature information loss while the incorporated convolutional block attention module (CBAM) attention mechanism enhanced the expressive capability of key features and strengthened the feature correlations in the spatial domain. Experimental results demonstrate that the proposed method achieves an average accuracy of 96.44% in the six actions recognition

verifying the feasibility of LTE signal-based human motion recognition.
