Abstract: A method, system and computer program product for filtering a RFID signal. At least one pre-operational interference signal is measured. Amplitude and frequency data are extracted from the at least one measured pre-operational interference signal. At least one filter-dependent parameter is computed based at least in part on the extracted amplitude and frequency data extracted from the measured at least one pre-operational interference signal. A table is generated during a pre-operational mode. The table has at least one set of filter coefficients based on the computed at least one filter-dependent parameter.

Abstract: A method and system for processing radio frequency identification ("RFID") communication device data, the method and system including measuring an energy level of a RFID signal received on a first communication channel, measuring an energy level of the RFID signal received on a second communication channel, selecting the communication channel with the greater energy level, and acquiring data samples from the RFID signal received on the selected channel. The method and system for processing RFID communication device data can further include generating a preamble from a series of the acquired data samples.
