Abstract :
Radio Frequency Identification (RFID) is a valid choice to achieve indoor localization simultaneously to the identification of objects. Measurements of Received Signal Strength (RSS) values show a higher variance for larger distances between tag and reader antenna. Therefore using a variable measurement noise in the localization algorithm is proposed. For the Constrained Unscented Kalman Filter (CUKF) the localization error is reduced by about 10%.
