Abstract
In one embodiment, a method for determining self-interference in radio full duplex includes transmitting, by a first radio transmitter and an antenna, a first signal and receiving, by a first radio receiver and the antenna, a reflection of the first signal. The method also includes estimating a channel in accordance with the first signal and the reflection of the first signal to produce an estimated channel and determining a second signal in accordance with the estimated channel. Additionally, the method includes transmitting, by a second radio transmitter, the second signal and removing a self-interference component of the reflection of the first signal to produce a corrected signal.
