Wireless indoor localization and tracking systems often implicitly assume that all anchors are continuously available. However, this assumption is often impractical under bandwidth and energy constraints. With limited wireless resources, tracking systems must balance localization accuracy with sensing and communication...

Conventional orthogonal frequency division multiplexing (OFDM) channel estimation relies on single-tap estimation and time-frequency (TF) interpolation, which becomes unreliable in high-mobility channels because Doppler-induced intercarrier interference (ICI) invalidates the underlying elementwise TF model. This paper...

Accurate indoor localization and tracking are foundational to next-generation location-based services. Although data-driven techniques offer strong modeling capabilities in complex indoor environments, they typically require labeled data for training and lack generalizability to unseen environments. In this letter, we...
This paper investigates environmental-sensing-aided proactive base station (BS) selection and beam prediction for millimeter-wave (mmWave) vehicle-to-infrastructure (V2I) wireless systems. We exploit onboard panoramic street-view images and a preloaded satellite map to predict communication-relevant environmental infor...
