Patent ID: 7342982

Claim:
A transceiver of a communication system, comprising: a front-end receiver for generating a first signal with a pre-cursor component and a post-cursor component according to a receiving signal, wherein the front-end receiver further includes an inverse partial response (IPR) filter to compensate an ISI introduced by a partial response filter in a transmitter part of a remote transceiver and an analog-to-digital (A/D) converter to receive an output signal of the IPR filter and convert the output signal to the first signal with a digital format; a noise canceller coupled to the front-end receiver for generating a second signal through eliminating the noise of the first signal; a Feed-Forward Equalizer (FFE) coupled to the noise canceller for generating a third signal through eliminating the pre-cursor component in the second signal according to a transfer function including a plurality of adjustable constants, wherein the adjustable constants includes a main-tap and the value of the main-tap is predetermined; and a decoder coupled to the FFE for decoding the third signal and eliminating the post-cursor component in the third signal.
