ABSTRACT:
A method of signal equalization of a transmitted bit stream by means of a feed forward equalizer is provided, whereby the signal is decomposed into at least two components and the components are multiplied with equalization parameters to form equalized components, which are superposed to form an equalized signal, and whereby conditional bit error rates by counting faulty transmitted bits in dependence of preceding and succeeding bits are determined and the equalization parameters are tuned dependent on the determined conditional bit error rates.
