Abstract:
1. A method for forming a transmitter-side transmission signal to compensate for the interference caused by transmission characteristics of an optical transmission system, comprising: forming a current bit pattern from a data bit to be transmitted and from adjacent bits of an N-stage shift register taken in a parallel manner and at a bit clock pulse rate; supplying the current bit pattern to a plurality of comparators; supplying an adjustable comparison value generated as a function of a compensation function to the comparators; transcoding the current bit pattern; to a bit combination via the comparators according to the comparison value, the current bit pattern transcoded into a bit combination corresponding to a digital value of a compensation signal; and converting the bit combination to an analog value of a compensation signal by digital/analog conversion, wherein the compensation signal controls a modulator according to the required formation of the transmission signal.
