Item tracking using radio frequency identification filtering

A wireless communication device, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and configured to:
• obtain a Radio Frequency Identification (RFID) observation corresponding to a plurality of backscatter signals from a plurality of RFID tags and based on an energizing signal, wherein each backscatter signal of the plurality of backscatter signals is indicative of an identifier of a respective RFID tag uniquely associated with a particular item of a plurality of items;
• determine expected background noise information corresponding to the RFID observation, wherein the expected background noise information is indicative of a subset of the plurality of items based on a comparison between a location of the wireless communication device and item placement information for the plurality of items;
• filter the RFID observation based on the expected background noise information, wherein a filtered RFID observation does not include information associated with the subset of the plurality of items indicated in the expected background noise information;
• and
• determine a basket content estimation based on the filtered RFID observation, wherein the basket content estimation is indicative of one or more collected items of the plurality of items.
