METHOD AND SYSTEM FOR DETECTING IMPULSE NOISE IN A BROADBAND COMMUNICATION SYSTEM
First Claim
1. A method for collecting time-domain data to be used for detecting presence of impulse noise on a communication system channel, comprising:
- creating a measurement interval during which no data signal can be transmitted on the channel;
acquiring voltage samples at a predetermined sample rate;
bandpass filtering the acquired voltage samples; and
storing the bandpass filtered samples to a working memory as elements of a one-dimensional array.

Abstract
A method halts transmission and/or reception of a desired signal on a channel in a communication network and samples an analog metric versus time on the channel at a predetermined sample rate. Successively sampled sets of data are stored first to a one dimensional array, each of which set is then stored to a two-dimensional array. The two dimensional array is analyzed in the time domain to determine the presence of impulse noise. Analog parameters represented by values contained in the samples can be analyzed to determine where, with respect to time, impulse noise occurs, and what is the amplitude of the impulse noise as well as AWGN.
