<p><P>PROBLEM TO BE SOLVED: To provide a circuit and method for canceling impulse noise in a multicarrier modulated signal. <P>SOLUTION: The method for reducing the noise in an equalized multicarrier modulated signal comprises the steps of estimating impulse noise in the equalized signal and removing a portion of the noise in the equalized signal as a function of the estimated impulse noise. The present invention has an excellent performance in comparison with prior art. For example, the embodiment of the present invention has a more enhanced symbol error rate of about 5 dB than the prior art. Further, such an enhancement may be in direct proportion to or in inverse proportion to the ratio of signals in the entire noise. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
