AN AUTOMATIC DSP-BASED CLASSIFIER FOR IMPAIRMENTS ON QAM MODULATIONS
Abstract
This paper presents an instrument for the automatic classification of the common impairments on Quadrature Amplitude Modulation (QAM) signals. The instrument is intended to help telecommunication service providers to guarantee Quality of Service (QoS) to their customers. Starting from an already developed method based on the processing of the constellation diagram image, the paper presents both significant improvements in the method and the realization of a prototype of impairment classifier, based on a multi-DSP hardware architecture. Experimental results of the validation phase of the realized instrument are presented, too.
