Original Abstract Submitted
The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The present disclosure relates to a method by a transmitting/receiving device, the method enabling: acquiring a time axis digital transmission signal; receiving a reception signal including a self-interference signal; extracting a time axis nonlinear signal sample from the time axis digital transmission signal; converting the time axis digital transmission signal and the time axis nonlinear signal sample into a frequency axis digital transmission signal and a frequency axis nonlinear signal sample; converting the reception signal into a frequency axis digital reception signal; estimating channel information of a self-interference channel, and a nonlinear signal coefficient of the self-interference signal, on the basis of the frequency axis digital transmission signal, the frequency axis nonlinear signal sample and the frequency axis digital reception signal; estimating the self-interference signal on the basis of the channel information and the nonlinear signal coefficient; and carrying out digital self-interference cancellation for the frequency axis digital reception signal by using the self-interference signal.
