Welcome to the Institute of Digital Signal Processing!

RFID Signal Processing

Radio Frequency IDentification (RFID) is a wireless data transmission and reception technique for identification of objects. It is believed that RFID can substitute the widely used optical barcode technology due to the limitations of the latter in (a) the barcode cannot be read from Non-Line-of-Sight (NLoS) tags, (b) the barcode typically needs personal care to be read, and (c) the limited information-carrying ability of the barcode. As a direct consequence the vast number of potential applications for RFID is basically uncountable (see e.g. the "forgotten objects scenario") and therefore provides many opportunities for challenging real-world scenarios.

DSV plans to merge the advances in RFID technology with sophisticated signal processing techniques and, in particular, aims to build up an RFID prototype system basically consisting of commercial available components being enriched with most recent technology and high-performance software.

Some representative questions being addressed in our RFID research:



Chipless RFID System and Testbed Workshop

DSV organizes a scientific workshop of "Chipless RFID System & Testbed" in the IEEE international Symposium on Antennas and Propagation APS/URSI 2015 which takes place in Vancouver, Canada, on 19-25 July 2015. More details about the workshop can be found here.


Chipless RFID Future and Challenges Workshop

DSV organizes a scientific workshop of "Chipless RFID Future and Challenges" in the 9th European Conference on Antennas and Propagation, EuCAP'15 which takes place in Lisbon, Portugal, on 12-17 APRIL 2015. More details about the workshop can be found here.
