Patent ID: 8532167

Claim:
A signal processing device utilized in a communication system, the communication system comprising at least a channel, the signal processing device comprising: a first feed forward equalizing unit, for performing a compensation operation according to a digital input signal so as to generate a first equalized signal; a first data slicing unit, coupled to the first feed forward equalizing unit, for generating a first output signal according to the first equalized signal; a first adding unit, coupled between the first feed forward equalizing unit and the first data slicing unit for generating a third output signal to the first data slicing unit and the second feed forward equalizing unit according to the first equalized signal and an interference eliminating signal; a second feed forward equalizing unit, coupled to the output of the first adding unit, for generating a second equalized signal according to the first equalized signal; and a second data slicing unit, coupled to the second feed forward equalizing unit, for generating a second output signal according to the second equalized signal; wherein a tap number of the first feed forward equalizing unit is smaller than a tap number of the second feed forward equalizing unit.
