A two-step pilot signal approach for distortion compensation and transmitter identification in wireless communication systems

In this paper, a methodology to identify the source of distortion, its compensation and application in a transmitter device identification process is proposed using a two-step pilot signal approach. Step one involves the estimation of the channel and the step two estimates the transmitter device parameters, which are used to compensate distortions and identify the device. The device identification process involves the comparison of the estimated transmitter device parameters with a validated set of parameters. Results from computer simulation show that the proposed compensation method has a significantly good performance in terms of the bit error rate of the system and successfully identifies the transmitter device.
