M. Rupp, J. Kaitovic, R. Langwieser:
"Signal Processing in RFID";
Talk: Seminar Duisburg, Duisburg, Deutschland (invited); 07-05-2012.

This talk introduces RFID signaling in the context of signal processing
for wireless communications. Passive tags are considered that have very
limited communication skills but can be produced in large amounts with
very low cost. Once a large amount of tags responses to a reader signal,
multiple collisions occur, hampering the throughput of such a system. We
first discuss potential improvements by MIMO technologies at the reader
without changing the tags. We further propose simple modifications of
the standard that could offer tremendous gains in throughput.
