ABSTRACT:
A radio frequency identification (RFID) decoding subsystem includes a pre-decode module and a decode module. The pre-decode module is coupled to process down-converted RFID signals into pre-decoded baseband data. The decode module is coupled to: enable a counting process based on the pre-decoded baseband data to produce a count resultant; and compare the count resultant with a threshold at a data bit interval to produce decoded RFID data.
