description An apparatus for communication includes a transmission chain, an interference suppressor and a reception chain. The transmission chain is configured to transmit a transmitted signal. The interference suppressor is configured to produce suppression signals, by filtering reference signals drawn from the transmission chain. At least one of the reference signals is filtered in a frequency domain. The reception chain is configured to receive a signal distorted by at least an attenuated and delayed replica of the transmitted signal. The transmitted signal and the received signal are (i) synchronized in time and (ii) each includes one or more subcarriers selected from a common subcarrier-resource. The reception chain is further configured to process the received signal up to selected points, to subtract the suppression signals from the received signal at the selected points to produce an interference-suppressed signal, and to recover data carried in the received signal from the interference-suppressed signal.
