Abstract
The primary obstacle in full-duplex (FD) communications lies in self-interference cancellation (SIC). Traditional FD systems often retain residual self-interference (SI) even after employing SIC techniques such as antenna isolation, spatial beam-forming, or the SI reconstruction and subtraction. In contrast, this work introduces an innovative FD transceiver design for SIC, grounded in the mathematical modeling of pseudo-Doppler (PD) shift systems. Our PD-aided transceiver design emerges as a highly effective SIC solution, capable of entirely eliminating SI from the center frequency of the transceiver’s desired signal. By employing a low-pass filter, the desired signal can be extracted without any residual SI contamination. Comparative analyses of SIC performance demonstrate that our transceiver design surpasses traditional FD systems, even when the latter achieve exceptionally high SI suppression levels.
