Abstract
A method for cancelling impulsive noise in a system of transmitting a band-limited baseband signal through a channel with a wider band than that of the baseband signal, in which an impulsive noise caused in the transmission channel is detected, to produce a detected output, from the received signal of the transmission channel outside of the frequency band of the band-limited baseband signal, and in which a cancelling pulse of reverse-polarity is produced as a pseudo noise pulse from the detected impulsive noise output and then superimposed on the original received signal, thereby cancelling the impulsive noise.
