Some Experimental Results on Impulse Noise Classification

The impulse noise that occurs on telephone channels affects the performance of data transmission systems more than it affects voice communications. As a step in constructing a more meaningful model of a telephone channel for use in data transmission studies, a computer-oriented classification technique to search for representative classes of impulse waveforms has been developed. Classes of impulses have been found experimentally in representative samples of actual noise from telephone channels. Results concerning these classes and the impulses in these classes are presented.
