Abstract

In this paper a multi-statistics model of the impulse noise is presented. An impressive experimental noise data collection acquired from digital access loops provides the synthetic noise environment with the most convenient probability density functions. Internal and external impulse noise sources within communications copper lines are briefly surveyed. A wide-band noise measuring circuit is used to determine the impulse noise properties. Our model gives a full description of the impulse statistics in the time and frequency domains, enables generation of impulses with statistically appropriate both time and spectral characteristics, is based on recent measurements and reflects the current statistics of impulse noise in digital networks, is based on wide-band measurements, agrees with empirical statistics from different access networks in different places.
