ABSTRACT:
A method of adjusting the weights of a blind equalizer. In the blind equalizer, an error signal e(n) is reset to zero as soon as the error signal e(n) reaches a predetermined value such as a maximum error signal value so that the weight vector W(n+1) is unaffected by the error signal e(n). Furthermore, the error signal e(n) is also reset to zero as soon as a second slicer output r2(n) changes from the original value due to an adjustment or transmission error and results in an inaccuracy of error signal e(n) so that the weight vector W(n+1) is unaffected by the error signal e(n).
