Abstract:
Wideband self-interference cancellation (SIC) in a full-duplex (FD) system requires the cancellers to achieve flat nanosecond-scale RF delay while minimizing the noise penalty to the receiver (RX). This work proposes: 1) cascadable hybrid low-noise first-order all-pass filters (APFs) in the first tap of the RF canceller to reduce the noise figure (…
