摘要：
Several modem communication systems are based on multicarrier transmission. In this contribution, some multicarrier transmission concepts are analyzed, which enable a reliable data transmission in spite of typical disturbances (intersymbol interference, interchannel interference, noise disturbances). Different equalizer strategies (e. g. data-directed equalization) in combination with different pulse shaping concepts (e. g. filtered multitone modulation and wavelet-packet modulation) are investigated under non-ideal channel conditions. The results show, that the equalizer has to take both disturbances (intersymbol and interchannel interference) in a multicarrier system into account, in order to obtain useful results.
