Abstract
Systems and techniques are provided for wireless communications. A Radio Frequency Identification (RFID) observation can be obtained based on an energizing signal and a plurality of backscatter signals from a plurality of RFID tags. Each backscatter signal can indicate an identifier of a respective RFID tag uniquely associated with a particular item of a plurality of items. Expected background noise information, indicative of a subset of the plurality of items for the RFID observation, can be determined based on comparing a location of a wireless communication device and item placement information for the plurality of items. The RFID observation can be filtered using the expected background noise information to exclude information associated with the subset of the plurality of items. A basket content estimation can be determined from the filtered RFID observation, wherein the basket content estimation is indicative of one or more collected items of the plurality of items.
