Abstract
In this paper, we proposed a novel and simple linear distortion compensation scheme utilizing Kohonen´s neural network for digital communications. The scheme compensates the distortions that exist in modulator and demodulator, at the decision stage in the receiver at the same time of data transmission and decision process. The scheme can compensate not only static but also changing distortions. Computer simulations using QPSK signal have confirmed the effectiveness of the proposed scheme.
