US Patent 7826520 Method and system for suppressing an interference signal

In a method for suppressing an interference signal during a transmission of data symbols between two transceivers, a transmit data symbol sequence is transmitted from a first transceiver to a second transceiver. An interference signal, which has occurred during the transmission of the transmit data symbol sequence, is detected in dependence on a received data symbol sequence, and the data symbol of the transmit data symbol sequence, which data symbol was transmitted last, is repeatedly transmitted from the first transceiver to the second transceiver when the interference signal occurs.
