Abstract

We present performance results for a new duplex scheme, called Zipper, for DMT-based VDSL (very high bit rate digital subscriber lines) systems on copper wires. This scheme divides the available bandwidth by assigning different subcarriers for the upstream and downstream direction. It has a high flexibility to divide the capacity between the up- and downstream as well as good coexistence possibilities with other systems such as ADSL (asymmetrical digital subscriber line). Simulation results show a high bit rate performance in different environments such as mixed ADSL and VDSL traffic, under radio frequency interference, and with different background noise sources
