Abstract: Uniqueness of radio frequency fingerprint is the foundation of transmitter recognition based on RF fingerprint. Mathematical model of RF fingerprint recognition system is constructed based on equivalent components having the same effect with overall transmitter components with manufacturing tolerance and drift tolerance. It is shown based on the model that component manufacturing tolerance, drift tolerance and ADC precision are principal influence factors of uniqueness of RF fingerprint. The tolerance-factor is validated in experiments. The results indicate that RF fingerprint is potentially unique.

Key words: RF fingerprint, uniqueness, influence factors, component tolerance
