Signal processing device having feed forward equalizing units with different tap numbers utilized in communication system

摘要

The present invention provides a signal processing device. The signal processing device includes a first feed forward equalizing unit, a first data slicing unit, a second feed forward equalizing unit, and a second data slicing unit. The first feed forward equalizing unit is utilized for performing a compensation operation according to a digital input signal so as to generate a first equalized signal. The first data slicing unit is coupled to the first feed forward equalizing unit, and utilized for generating a first output signal according to the first equalized signal. The second feed forward equalizing unit is coupled to the first data slicing unit, and utilized for generating a second equalized signal according to the first equalized signal. The second data slicing unit is coupled to the second feed forward equalizing unit, and utilized for generating a second output signal according to the second equalized signal.
