Patent ID: 7061978

Claim:
A method for reducing intersymbol interference (ISI) products within a data signal, comprising: receiving an input data signal that includes a first plurality of ISI products and corresponds to a detected data signal received via a signal transmission medium; adaptively equalizing said input data signal to provide a first equalized signal; selectively equalizing and processing said input data signal and at least a portion of an output data signal to provide a processed signal by adaptively equalizing said input data signal to provide a second equalized signal, slicing said second equalized signal to provide a sliced signal, and nonlinearly processing said sliced signal and said at least a portion of said output data signal to provide said processed signal; subtracting said processed signal from said first equalized signal to provide a resultant signal; and processing said resultant signal to provide said output data signal that includes a second plurality of ISI products which is smaller than said first plurality of ISI products.
