It has been found more necessary in evaluating data-transmission systems to consider impulsive noise than conventional Gaussian noise. In this letter, a model of impulsive noise is assumed which is reasonably consistent with the measurements and is not too complex to be handled analytically. Various digital-modulation systems are analysed to determine their performance in such a noise environment. Bit-error rates are calculated as a function of average signal/impulsive-noise ratio. The ranking of the various systems with respect to immunity against impulsive noise is found to be almost the same as to that for Gaussian noise.
