Enabling 4-D Sensing in MU-MIMO-OFDM: A Block-Wise Signal Design With Double-Orthogonal Radar Supplement

This paper proposes a novel multi-user multiple-input multiple-output orthogonal frequency-division multiplexing (MU-MIMO-OFDM) based integrated sensing and communication (ISAC) framework. By partitioning the time-frequency resource grid into sub-blocks, the architecture enables 4D sensing (range, velocity, azimuth, el...

Environment-Aware Generalized Wireless Localization via Transformer

Wireless localization is expected to play a key role in future communication systems by providing location-aware services and supporting efficient network operation. However, existing deep learning (DL)-based localization methods often suffer from limited generalization when the deployment environment changes, since th...
