Though the decision directed least mean square error algorithm (DD-LMS) has small residual error, when the channel eye close, it can not converge. That is, it has no cold start ability.
It used the moving leastsquare approximation as a trial function, and used the weighted function of the moving leastsquare approximation as a test function of the weighted residual method.
