 The forgetting factor is used with the RLS algorithm in a DFE for calculating the tap-coefficient vector in order to minimize the squared equalization error due to input noise and due to channel dynamics. Recursive least squares (RLS) algorithm with a constant forgetting factor is often used to update the tap-coefficient vector of the DFE for ISI-free transmission. The rule for operation of the Hamiltonian matrix on the configuration coefficient vector in this representation is reduced to the operations of Coulomb and exchange interaction, without requiring transformations of the molecular integrals. The coefficient vector for this specification was unstable and became increasingly negative during the 1980s.
