Revolutionizing STAR Transceivers through Electric + Acoustic SIC

Simultaneous-transmit-and-receive (STAR) or full-duplex (FD) transceivers are challenged by the tremendous self-interference from the transmitter to the receiver. This self-interference is typically much larger than the desired signal and undergoes substantial frequency dispersion due to long delay spreads in the self-interference channel. This work will present several innovative concepts that include quasi-electrostatic (switched-capacitor) delay lines, active noise-cancelled self-interference cancellation, metamaterial/switched-resonator-based delay lines and embedded sensing and machine learning-based control.
