Integrated Sensing and Backscatter Communication

This research line introduces integrated sensing and backscatter communication (ISABC), where a base station simultaneously supports communication and sensing through the same transmitted waveform. Instead of treating the reflected signal as a by-product, the reflected signal from passive tags becomes a shared resource: it carries data to the user while also revealing environmental or tag-state information to the base station.

Across the letter, journal, and magazine works, the idea evolves from a first system model to optimized multi-tag beamforming and then to a broader ambient-IoT vision. The animation below highlights that progression through a single visual story.
