Brief survey on full-duplex relaying and its applications on 5G

This paper gives an brief survey on full-duplex relaying. First, we discuss the importance of full-duplex communications and its major drawback, known as self-interference. We provide a overview of the state-of-the-art on self-interference cancellation techniques from antenna design to digital cancellation. Then, we assess current developments in full-duplex relaying, some promising protocols and we discuss some of the performance analysis carried out so far. Finally, we discuss the importance of full-duplex, more specifically full-duplex relaying, on 5G networks.
