IDENTIFYING WIDEBAND IMPULSE NOISE THROUGH A GROUP OF SMALL CHANNELS

摘要

Methods, systems, and computer readable media can be operable to determine impulse noise over a wide spectrum based upon measurements of impulse noise associated with each of a plurality of channels. Impulse noise can be observed on each of the plurality of channels and the observed impulse noise signals can be summed together. In summing observed impulse noise signals, a Fourier transform can be used to convert the observed impulse noises from a time domain representation to a frequency domain representation. The sum of the impulse noises can represent the impulse noise existing on the wide spectrum and can be converted from a frequency domain representation to a time domain representation using an inverse Fourier transform.

1. A computer-implemented method comprising:
identifying a subset of channels within a wide spectrum; performing a bandwidth-limited impulse noise measurement within each of the identified channels; converting the bandwidth-limited impulse noise measurements within each of the identified channels to a frequency domain representation; summing the frequency domain representations of impulse noise from the identified channels, thus creating a frequency domain representation of impulse noise over the wide spectrum; and converting the frequency domain representation of impulse noise over the wide spectrum to a time domain representation of impulse noise over the wide spectrum.
