Abstract :
An approach for equalizer design based on the impulse response symmetry is presented. Design is based on nonlinear optimization. Analytical goal function is given and the appropriate choice of initial solution is proposed. Behavior of a typical error surface is discussed and compared to the surface obtained by numerically approximated goal function. Position of the symmetry line is analyzed and the goal function is modified in order to obtain theoretically the best symmetry for a given system.
