Abstract
Co-frequency Co-time Full Duplex (CCFD) is a key concept brought up in 5G, of which the key technology is self-interference (SI) cancellation. Among all the cancellation technology, the digital cancellation technology has the advantage of being flexible and efficient, and further improving its performance is an important way to reduce the cost, power consumption and complexity of full-duplex nodes. In this paper, an adaptive filtering scheme based on channel estimation is proposed, and the two important processes of SI channel estimation and adaptive filtering are analyzed. Finally, the performance of the scheme is verified by MATLAB simulation.
