  Abstract

DSL(digital subscriber line) transceiver designers have concerned the impulsive noise as well as NEXT(near-end crosstalk) and FEXT(far-end crosstalk) immunities known as the strongest sources that limit the DSL channel capacity. In these noise environment the analysis on the performance of DSL should be needed.
Therefore, in this paper we have estimated and simulated the SNR(signal-to-noise ratio) margin of DMT (discrete multi-tone) signal in Gauss, NEXT, FEXT and impulse noise environment by modeling an Middleton's Class A impulse signal with the test Cook pulses. As a result, it is known that the transmission rate of uplink is limited by noise characteristics rather than by loop length, but that of downlink limited complexly by both of noise characteristics and loop length.
In conclusion, these results will be utilized as the threshold of ADSL performance in the complex noise environment including impulse noise.
