MITIGATION OF RADIO FREQUENCY INTERFERENCE IN MULTICARRIER TRANSMISSION

摘要

A multi-carrier information transceiver that exhibits robustness against rad io frequency interference (RFI) signals present in the communications channel. The transceiver includes a RFI mitigation technique that operates not only during the steady state operation of the transceiver but also during the training stage of the transceiver. That requires dynamically modifying the training signals when the presence of RFI is detected. The modification of t he training signals facilitates the estimation of RFI, improving the performanc e of the multi-carrier transceiver.
