Patent ID: 8270461

Claim:
A signal processing device utilized in a communication system, the communication system comprising at least a channel, the signal processing device comprising: an analog-to-digital converter (ADC), coupled to the channel, for performing an analog-to-digital converting operation on an analog input signal of the channel to generate a digital input signal; a first adding unit, coupled to the ADC, for generating a first output signal according to the digital input signal and an interference eliminating signal; a feed forward equalizing unit, coupled to the first adding unit, for compensating the first output signal to generate an equalized signal a data slicing unit, coupled to the feed forward equalizing unit, for generating a second output signal according to the equalized signal; a second adding unit, coupled between the feed forward equalizing unit and the data slicing unit, for generating a third output signal according to the equalized signal and the second output signal; an infinite impulse response (IIR) compensating unit, coupled to the second adding unit and having a compensation parameter, for performing a compensation operation by multiplying the third output signal by the compensation parameter so as to generate a fourth output signal; and an interference eliminating module, coupled between the first adding unit and the IIR compensating unit, for generating the interference eliminating signal according to the fourth output signal.
