摘要： A device for reducing a self-interference contribution in a full-duplex wireless communication system configured to transmit a transmission signal and modulated by a baseband signal, and configured to receive a reception signal containing a self-interference contribution corresponding to the transmission signal, the reduction device comprising a first reduction module, configured to take a replica of the transmission signal, and configured to generate a first reduction signal, the device further comprising: a second reduction module, arranged so as to be able to take a replica of the baseband signal, and capable of generating a second reduction signal that is a function of the temporal derivative of the baseband signal, a subtractor, linked to the first reduction module and to the second reduction module, and configured to subtract from the reception signal the first reduction signal and the second reduction signal.
