Patent ID: 7130341

Claim:
A method of signal equalization of a transmitted bit stream by means of a feed forward equalizer, comprising the steps of: decomposing said signal into at least two components, determining conditional bit error rates by counting corrected faulty-received bits dependent on preceding and succeeding bits, tuning equalization parameters dependent on the determined conditional bit error rates, multiplying said components with said equalization parameters to form equalized components, and composing an equalized signal by superposition of said equalized components; wherein the step of decomposing said signal comprises the step of decomposing said signal into at least three components, which are delayed with respect to each other; wherein the step of determining conditional bit error rates comprises the steps of: determining a first conditional error rate so that the values of the preceding bits are equal to the values of the corrected faulty-received bits, determining a second conditional error rate so that the values of the preceding bits are different from the values of the corrected faulty-received bits, determining a third conditional error rate whereby the values of the succeeding bits are equal to the values of the corrected faulty-received bits, and determining a fourth conditional error rate whereby the values of the succeeding bits are different from the values of the corrected faulty-received bits.
