Our Group Paper Accepted at ISCASSP 2020

Our paper on “On Measuring Doppler shifts between tags in a Backscattering Tag-to-Tag Network with application in tracking” was accepted at 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP).

This paper presents a technique where by passive tags can track each other in a backscattering tag-to-tag network (BTTN). We achieve the same accuracy for doppler shifts with approximately as that achieved by active conventional RFID readers. Our median tracking error based on data from two tags is only about 2.5 cm.
