ABSTRACT:
An equalizer apparatus comprises a first filter (406) having a first respective plurality of filter coefficients, a channel model filter (414) having a plurality of model filter coefficients, and an adaptive algorithm unit (416). The adaptive algorithm unit (416) is arranged to adapt at least a first predetermined number of the first respective plurality of filter coefficients and at least a second predetermined number of the plurality of model filter coefficients in response to an error signal (e) corresponding to a difference in filter output signals from the first filter and the channel model filters (406, 414). The adaptive algorithm unit (416) operates in accordance with a respective state channel estimation technique. The respective state channel estimation technique is adapted so as to reduce a number of states allocatable to at least one of the plurality of state-defining taps, thereby reducing an overall number of states definable associated with the plurality of state-defining taps. The channel model filter (414) is adapted a number of times corresponding to the reduced overall number of states.
