Abstract
Full-Duplex transmission is an important technology to improve spectral efficiency. By contrast with traditional half-duplex transmission, Full-Duplex allows node to transmit and receive simultaneously on the same frequency bands. It can significantly improve the spectral efficiency. However, due to the simultaneous transmission and reception, it will result in self-interference from the transmitter to the receiver. Thus the key to full-duplex transmission is first to resolve issues arising from self-interference. In this thesis, we study full-duplex transmission applied particularly on the relay. We first consider one way transmission, and assume that there is no processing delay in relay’s transmission. In this regard design the combining matrix and precoding matrix to maximize the channel capacity of full-duplex relay channel. We then consider two-way relay channels, and also take the processing delay into account. In this system with self-interference suppressed the maximum sum rate is analyzed. Finally we will compare full-duplex relay networks with half duplex ones.
