Abstract
A cross-division duplex (XDD) system includes an apparatus having a transceiver configured to communicate via an uplink channel and a downlink channel concurrently. The apparatus also includes a transmit antenna, a receive antenna, and a processor. The processor is configured to: estimate a non-linear component corresponding to a transmit path in the transceiver; apply an equalizer function to a received signal; and subtract, in a self-interference cancel (SIC) circuitry, the estimated non-linear component from the equalized signal.
