We introduce an RF fingerprint for non-destructive cellular device identification. The new proposed fingerprinting algorithm is a data-driven technique based on a singular value decomposition of a user equipment's symbol-constellation points. We explore the effectiveness of the fingerprint technique with a test set of real devices and show experimentally that this fingerprint is robust to device positioning errors and measurement noise.
