ABSTRACT:
The invention relates to a device and a method for increasing the bandwidth in a line-connected multicarrier system, the characteristic properties, estimated by a channel estimator of a transmission channel being interpolated/extrapolated by an interpolating/extrapolating device. An equalizer device performs additional equalization of affected carriers in dependence on these interpolated/extrapolated properties, a bit loading device being adapted in dependence on the additional equalization. In this manner, further carriers are available for the data transmission which increases a bandwidth.
