In this article, we propose three channel impulse response (CIR) based physical layer authentication schemes, which exploit the inherent properties of CIR to enhance the authentication reliability under a binary hypothesis testing in mobile communications. Specifically, the reliability of authentication is enhanced by mitigating the noise components of CIR estimates, deriving CIR difference based on a channel predictor, and observing multiple CIR differences in the final decision, respectively.
