Abstract : aussian impulse noise source which can be used to model the impulsive noise present in wideband communications systems. The impulsive noise appearing on practical systems is characterized by bursts of much higher amplitudes than would be predicted by a normal- or Gaussian-distribution law. The impulse noise model and the actual hardware noise generator described in this paper are capable of producing Gaussian background noise, lognormal impulsive noise, and burst timing to set prescribed starting and ending times of the bursts and impulse density within each of the burst periods. The techniques used in this paper are based on first generating a basic Pseudo Random Binary Sequence (PRBS) generator and, from this, deriving the Gaussian background noise by adding samples from the PRBS generator.
