In this paper, we propose the concept of digital interference cancellation as an effective solution to mitigate the induced self-interference due to energy coupling in full duplex communication (FD) channels. A Least Mean Square (LMS) adaptive digital filter is incorporated at each transmitting/receiving node and the desired signal is obtained by subtracting a reference signal from the received one. For verification purposes, a multimedia signal, specifically, voice, is applied as a received data at a terminal that is in a transmission state with the presence of an additive white Gaussian noise (AWGN). Different examples utilizing audio signals are presented and discussed. The recovered data validates the designed scheme.
