ABSTRACT:
A digital transmission system comprising a receiver with cascaded equalizers. The transmission system may also include multicarrier modulation means and multicarrier demodulation means comprising a semi-fixed equalizer cascaded with an adaptive equalizer. The semi-fixed equalizer equalizes the relatively stable or slowly and/or slightly changing imperfections which are due to the channel and the adaptive equalizer equalizes the imperfections which are due to transmission noise. The invention likewise relates to a process for determining the characteristics of the semi-fixed equalizer.
