In this dissertation, we study MIMO two-way relay networks consisting of singleantenna
users which wish to exchange information with the help of multiple multiantenna relays. The …

Both two-way relays (TWR) and full-duplex (FD) radios are spectrally efficient, and their
integration shows great potential to further improve the spectral efficiency, which offers a …

In this paper, we propose a cognitive transmission scheme for Amplify‐and‐Forward (AF)
two‐way relay networks (TWRNs) and investigate its joint sensing and transmission …

In this paper, we investigate the secrecy outage probability (SOP) for the cooperative amplify-
and-forward (AF) two-way relay networks (TWRN) with channel estimation (CE) errors under …

In this paper we propose an adaptive channel estimation scheme for Amplify and Forward
(AF) two-way relay systems with frequency selective and fast varying channels. The …

ABSTRACT A major challenge in MIMO-OFDM systems is how to obtain the channel state
information accurate and prompts for coherent detection of information symbols and in …

Most existing studies on two-way relay networks (TWRNs) typically assume that the
channels are reciprocal. However, in time-frequency dispersive channels, the channels …

In this paper, we propose a novel linear beamforming scheme for multiuser two-way MIMO
relay channels to maximize the system sum rate. To achieve a low complexity, our scheme is …

In this paper, a code-aided maximum likelihood (ML) iterative algorithm is proposed for
amplify-and-forward (AF) two-way relay multicarrier code division multiple access (MC …

This paper discusses a joint adaptive channel estimation and transceiver design scheme for
MIMO two-way relay systems. In order to reduce the computational complexity at the …
