Abstract
We propose a novel and simple linear distortion compensation scheme utilizing Kohonen´s self-organizing maps (SOM) network for digital wireless 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 signals have confirmed the effectiveness of the proposed scheme.
