In this paper electronic feed forward
equalization is performed to mitigate the link chromatic dispersion. The
equalizer coefficients are computed by a decision-directed process based on the
sign-sign least mean square and the recursive least square algorithm.
Therefore, this paper evaluates the performance of these algorithms in
chromatic dispersion compensation at bit rate of 10 Gb/s. This paper compares
these two adaptation algorithms for receiver based on analogue electronic
dispersion equalizers by simulation and experiment. This paper concluded that
recursive least-square algorithm is computationally more complex than sign-sign
least mean square algorithm since matrix inversion is required, but achieves
