Abstract
The present invention is directed toward the recovery of RFID signals from RFID credentials. The recovery and subsequent interpretation of RFID signals may be accomplished by providing a set of predetermined probabilities for the occurrence of a symbol after another symbol in a received signal. The predetermined probabilities may be dependent only upon the encoding scheme used, thereby providing a more robust and less processor intensive decoding protocol than has previously been contemplated.
