Patent abstract
Error contributions in a DMT system where a received DMT-signal is effected by intersymbol interference, intercarrier interference and additive noise are minimized. Intersymbol interference average power, intercarrier interference average power, and additive noise average power are calculated. A cost function is determined by adding the intersymbol interference average power, the intercarrier interference average power, and the additive noise average power. A constraint is introduced which avoids a trivial solution where a time domain equalizer (TEQ) vector is equal to zero. The cost function is minimized by optimizing the TEQ vector.
