COMBATING SIGNAL INTERFERENCE IN DIGITAL TRANSMISSION.

摘要

A device and method for removing signal interference from a digital signal by using an adaptive filter which tunes to the periodic components of the interfering signal. The output of the adaptive filter is then subtracted from the received signal to produce an error signal. This error signal is then used to recursively update the taps of the adaptive filter. The invention also relates to the use of the adaptive filter in conjunction with a DFE.
