Abstract :
A novel method for FIR filter control optimization is proposed to expand the chromatic dispersion compensation range in electrical digital signal processing systems in transmitters and receivers. A reduction of the number of coefficients of FIR filter by 40% is observed, which allowed to reduce the instability occurred by mis-configuration during the filter control.
