    Generalization Theory for Through-the-Wall Radar Human Activity Recognition

    Weicheng Gao

    cs.IT · cs.LG · eess.SP

    Through-the-wall radar (TWR) human activity recognition (HAR) is important for non-line-of-sight indoor sensing, security monitoring, and emergency rescue. However, structured distribution shifts caused by person variation, observation-view variation, and wall-condition variation severely degrade recognition generalization, while the origin of the target-domain error still lacks a rigorous theoretical explanation. To address this issue, a...

    RadioDiff-v2: Generative Angular Radio Maps for Multi-Beam Selection and Localization

    Xiucheng Wang, Junxi Huang, Nan Cheng

    cs.IT · cs.LG · eess.SP

    Angular radio maps describe the received-power distribution over the angle of arrival and underpin beam selection and receiver localization in sixth-generation (6G) networks. Predicting the angular power spectrum (APS) from geometry is difficult, because the mapping is ill-posed in non-line-of-sight (NLOS) conditions and must generalize to unseen environments. Distortion-minimizing regressors return the conditional mean, which over-smooths...
