<p>The present invention relates to methods and arrangements to minimize error contributions in a DMT system where a received DMT-signal is affected by intersymbol interference, intercarrier interference and additive noice. The method comprises the following steps: - Calculating intersymbol interference average power. - calculating intercarrier interference average power. - Calculating additative noice average power. - Calculating a cost function by adding the intersymbol interference average power, the intercarrier interference average power and the additative noice average power. - Introducing a constraint, which avoids a trivial solution where the TEQ vector is equal to zero. - Minimizing the cost function by optimizing the TEQ vector.</p> |
