Nonintrusive measurement of impulsive noise in telephone-type networks

An in-service, nonintrusive technique for the characterization of impulsive noise in telecommunication systems is presented. It is based on the segmentation of the signal observed during a telephone call in speech and noise frames. The signal observed during noise frames is further processed by means of a hypothesis testing procedure in order to detect the presence of impulses. Experimental results that show the effectiveness of the proposed technique are presented and discussed.
