For example in case of an OFDM multicarrier transmission system the transmission characteristics of subcarriers of a multicarrier transmission system using a plurality of antenna elements ( 3, 3 ') can be adjusted. Particularly the power and the phase of the subcarriers can be adapted. To this object the subcarrier frequency channel ( 2, 2 ') characteristics of the multicarrier transmission are detected ( 11, 11 ') at the side of the transmitter ( 3 ). The power of each subcarrier is then distributed by a weighting unit ( 14, 14 '). The subcarriers can be further pre-equalized ( 1, 1 ') by dividing the subcarrier signal respectively by the sum of the squared magnitude of the frequency channel characteristics of all subcarrier signals or a frequency characteristic of the selected antenna element ( 3, 3 ').
