In this paper, we consider the use of filterbank based multicarrier modulation for VDSL transmission. We compare two filterbank optimization criteria, i.e. the maximization of the time-frequency localization and the minimization of the out-of-band energy and we show that filterbank optimized according to the time-frequency criterion achieve better rates and allow the use of reduced size equalizers.
