Abstract: An apparatus for reducing interference of a signal over a plurality of stages includes a processor configured to determine at least two equalizer taps based on at least one of a covariance and a channel impulse response of the signal. The processor is further configured to estimate at least one additional equalizer tap based on the at least two equalizer taps. In addition, the processor is configured to reduce, for each of the plurality of stages, the interference of the signal for that stage using an equalizer tap from either the at least two equalizer taps or the at least one additional equalizer tap, so that the signal for the next stage in the plurality of stages has the reduced interference. A method is also provided for reducing interference of a signal over a plurality of stages.
