Abstract

In a process of producing electronic components, the components are never exactly the same. This causes the output signal from radio transmitters (even similar ones) to be different. The differences are negligible, so it does not violate telecommunications standards. But these inherent and unique differences can be considered as physical layer features and used to authenticate radio transmitters. Normally, authentications based on software can be forged. Forgery based on the inherent characteristics of radios is very difficult or impossible. Because it requires a lot of knowledge, money, and time. The power amplifier is the last part of the transmitter. So it has the most effect on the transmitter output signal. In previous researches, the receiver assuming to have the SNR value of the received signal, used the coefficients of the power amplifier nonlinear model to classify the transmitters. In this paper, a new feature is provided to perform authentication operations independently of the SNR value of the received signal. The simulation results show that using the proposed new feature, the radio transmitter authentication process from low SNR values (at least 15dB) to high ones, without the need for SNR measurement, is performed well with a likelihood of more than 80% success.
