Distinguished Lecture: On-Chip Self-Interference Cancellation for Full Duplex Radios and Other Applications
November 10, 2021 @ 3:15 pm – 4:15 pm
Several efforts of the last decade have demonstrated the ability of a radio transceiver to simultaneously transmit and receive using the same frequency band – this is commonly referred to as in-band full duplex communication.
This presentation will explore similarity and differences between the problem of self-interference/signal cancellation in very diverse applications from the perspective of noise, linearity, cancellation bandwidth, convergence of adaptation algorithms and suppression depth. Two examples of integrated self-interference cancellation will be presented (i.e., for neural interfaces and wireless communication) that define the state-of-the-art with respect to linearity, noise and the ability to adapt on-chip cancellation filters in real time.
