摘要：
An input estimator is based on a combined MFDQ-DF and trellis for use in, for example, an ADSL environment. In particular, for an ADSL implementation, the system will have one feedback tap for the decision feedback. However, it should be appreciated that the idea and basic concept of using the structure of a trellis to aid in determining the feedback point can be extended to any system using a feedback equalizer to estimate input to a trellis decoder.
