This letter presents a device identification method based on the distortion of a power amplifier (PA). The distortion of PA is measured by a logarithmic swept sine, which can distinguish harmonic distortion for each order. In this letter, we propose a new feature extraction utilizing each harmonic distortion to accurate device identification in a multipath environment. The proposed method can reduce computational complexity because it requires no calculation of the pseudoinverse matrix and iterative calculation. Experimental results show that the proposed method can achieve a higher identification ratio in an indoor environment.
