This paper faces the problem of the automatic classification of the stresses affecting the quadrature amplitude modulation. This problem arises when a continuous monitoring system is needed for improving the quality of service in communication networks based on such a modulation scheme. In particular, a measurement method based on image processing is proposed. It automatically analyzes the constellation diagram and selects the stress actually present through a template matching technique. The results of the first simulations, carried out on signals affected by different stresses and SNRs, are presented and discussed. Some experimental results are also shown.
