摘要：

Demand for high speed digital transmission on ordinary phone lines motivates the introduction of VDSL. This paper investigates the VDSL transmission environment. The channel is shown to be difficult for high speed digital transmission and sophisticated signal processing methods are required for reliable transmission. This paper also describes various transmission schemes that are proposed to support high data rates in the difficult transmission environment. Two schemes, SDMT and QAM/CAP, are compared in terms of SNR margins and computational complexity.
