Kurzfassung englisch:
RFID readers for passive tags generally suffer
from self-interference. The transmitter of the RFID reader
is also in operation during receive periods to power the
tag and enable backscatter modulation. The state-of-the-art
solution employs a leaking carrier canceller, which needs to be
adjusted. The proposed fast algorithm provides a starting point
for conventional gradient based approaches, which already
improves isolation by 7.2 dB at least. It is based on three scalar
measurements, and does not demand for special hardware. The
algorithm was tested on our RFID testbed and experiments
show a significant decrease of steps necessary to reach the
final leaking carrier canceller setting.
