The paper faces the problem of the automatic classification of the stresses affecting the
quadrature amplitude modulation (QAM). This problem arises when a continuous monitoring
system is needed for improving the quality of service (QoS) in communication networks
based on such a modulation scheme. In particular, a method based on image processing is
proposed. It automatically analyses the constellation diagram and selects the stress actually
present through a template matching technique. The results of the first simulations, carried …
