Analytical Solution of Optimal Electrical Equalization Coefficents
G. Katz, Dan Sadot · 2006 IEEE International Conference on Communications · 2006
Electrical dispersion compensation equalizer is a key and cost-effective element in optical communication OOK systems in the presence of chromatic dispersion. Here, for the first time, to the best of the authors' knowledge, an analytical solution is established for the electrical equalizer coefficients in an optical communication system. The solution is based on minimum mean-square error criterion. The analytical results show a perfect match with computer simulation. In addition BER performance comparison with the adaptive least mean square (LMS) method reveals that the analytical solution performs better due to LMS excess mean-square error.
