APPARATUS AND METHOD FOR CONSTRAINING THE VALUE OF FEEDBACK FILTER TAP COEFFICIENTS IN A DECISION FEEDBACK EQUALIZER |
摘要 |
An apparatus and method is disclosed for reducing error propagation in a decision feedback equalizer by constraining the values of feedback filter tap coefficients in a feedback filter of the decision feedback equalizer. Thefeedback filter tap coefficients that are constrained are calculated using a constraint cost function and a related constraint function. The constraint condition of the present invention reduces error propagation in a decision feedback equalizer by preventing error from circulating in a feedback loop of a feedback filter within the decision feedback equalizer. |
