Modelling XDSL Lines under Crosstalk Effect

In recent years, digital subscriber line (DSL) technology has been gaining popularity as a high speed access technology, thanks to its capability of delivering multimedia services. The major impairment for DSL technologies is crosstalk in the telephone lines. Therefore,in order to overcome this noise effect in DSL lines, complicated error mitigation and framing techniques have to be used in DSL systems. In this work, the crosstalk model of DSL lines is given, and the effect of crosstalk on the channel capacity of ADSL services (the most widely used DSL service type) is investigated.
