Impulse noise performance of an asymmetric digital subscriber lines passband transmission system

This letter presents an analytical method to numerically evaluate the bit error Probability (BEP) performance of a quadrature amplitude modulation (QAM) transmission system in the presence of impulse noise. This work facilitates characterization of the two-wire twisted-pair loop plant for high-speed digital communications. Simulation results are presented to demonstrate the effectiveness of this approach using parameters that are typical of the recently proposed Asymmetric Digital Subscriber Lines (ADSL) for high-speed digital transmission over local copper telephone loops.<>
