Abstract
The present application describes a method for characterizing a self-interference channel of a frequency division duplex transceiver including a transmitter and a receiver. The method includes transmitting, from a transmitter of a frequency division duplex transceiver in a transmission band, a transmission signal including a message signal and a swept tone that changes frequency from below an upper edge to above a lower edge of a reception band of a receiver, the self-interference channel being defined between the transmitter and the receiver of the frequency division duplex transceiver, such that at least a portion of the message signal leaks into a signal received the receiver, determining, at an infinite impulse response (IIR) filter of the receiver, an infinite impulse response of the self-interference channel based upon a reception of the swept tone swept at each frequency in the reception band, and estimating the self-interference channel, based upon the infinite impulse response.
