Abstract: Systems and methods for a full-duplex backscatter system. An example method includes outputting, via a transmitter of the backscatter system, a single tone carrier for transmission via an antenna of the backscatter system. A tunable impedance network is tuned via a microcontroller to reduce self-interference associated with the signal tone carrier by at least a threshold level, with the tunable impedance network including passive elements which are configured to be tuned, and with the self-interference reduction by the threshold level being in the analog domain. Backscatter data packets are received via a receiver from backscatter tags, with the backscatter data packets being associated with an offset frequency and are decoded by the receiver.
