Abstract

In this paper, circuit aspects of equalizers and crosstalk compensation filters for DFT transmultiplexer filter banks are considered. These filters are used to eliminate intersymbol interference and crosstalk in multicarrier data transmission systems with nonideal transmission channels. To get knowledge about structure and computational efficiency of these filters, they are analyzed and the remaining error is evaluated as a function of equalizer length, number of channels, group delay of the channel, and some filter parameters
