Abstract
A repeater includes a first coupler receives a first guided electromagnetic wave that propagates along a surface of a transmission medium without requiring an electrical return path, the first coupler generating a first received signal in response to the first guided electromagnetic wave. Impulse cancellation circuitry generates a first impulse noise signal in response to impulse noise in the first received signal. Transceiver circuitry generates a first transmit signal based on the first received signal and the first impulse noise signal, wherein the transceiver circuitry cancels the first impulse noise signal when generating the first transmit signal. A second coupler converts the first transmit signal to a second guided electromagnetic wave that propagates along the surface of the transmission medium without requiring an electrical return path.
