Abstract :
This paper presents a framework for estimation of data errors due to impulse noise in xDSL systems. The analysis is based on a new DSL-oriented impulse noise model derived from recent studies in the German and British telephone networks. The data errors in ADSL are estimated theoretically at symbol, bit, frame level. All relevant framing characteristics have taken into account, such as adaptive bit loading, forward error correction, and interleaving. The approach is shown to offer good approximation to simulation results, and can also be used for next generation of DSL systems - VDSL.
