TRANSMISSION SUPPRESSION

摘要

A transmission suppression apparatus includes a first modulator that converts a symbol to a waveform. The apparatus further includes a first non-linear filter, configured to at least partially compensate for non-linear distortions of a transmission signal path. The apparatus further includes a first medium coupling device for coupling signals to a communication medium. The apparatus further includes a second medium coupling device for coupling signals from the communication medium. The apparatus further includes summing circuitry with a first input connected to an output of the second medium coupling device. The apparatus further includes cancellation circuitry, connected to a second input of the summing circuit, that converts the symbol to an analog waveform that is substantially 180 degrees out of phase with the analog waveform encoding the symbol on the first input to the summing circuit.
