ABSTRACT:
Equalization techniques are disclosed to reduce intersymbol interference of a received signal. Intersymbol interference is reduced by feedforward filtering and adjusting the input to the feedforward filter with feedback. This approach facilitates the removal of intersymbol interference from sparse signal portions before sparseness is undermined by other equalization procedures. Also, multiplication operations may be reduced and limited multiplier resources more effectively allocated by applying a threshold test to various multiplier coefficients associated with the equalization technique.
