This paper focuses on one of the major challenges
in RFID reader receivers, namely the data synchronisation
and decoding at the RFID reader. According to the
most widely used RFID standards, the data rate in RFID tag
to reader communications is subject to variations within more
than one decade, and may deviate from its nominal frequency
up to 22%. This results in strong difficulties in synchronising
and decoding this data at the receiver of the RFID reader.
In order to achieve synchronisation and decoding, a sophisticated
algorithm based on correlations is presented. The
algorithm is optimised in terms of resource consumption to be
processed on an FPGA or ASIC. Implementation details are
presented as well as measurements, showing the performance
of the receiver.
