Multiple antennas have played an essential role in spatial multiplexing and diversity
transmission for a wide range of communication applications. Most advances in the design …

In this paper, secure wideband beamforming design is investigated for two-way multiple-
input multiple-output (MIMO) relaying systems with one eavesdropper. Due to the wideband …

We consider a single-carrier asynchronous two-way amplify-and-forward relay network,
where two single-antenna transceivers exchange information with the help of several single …

We consider the problem of joint power allocation and distributed beamforming design for
asynchronous two-way multi-relay networks, where two transceivers rely on an orthogonal …

We study the problem of optimizing the end-to-end performance of a full-duplex filter-and-
forward MIMO relay link, consisting of a source, a relay, and a destination node, by …

In this study a new approach to filter‐and‐forward (FF) relay design in an overlay cognitive
radio (CR) network with frequency selective channels is proposed. In this system, to …

We consider multi-carrier two-way relaying networks consisting of two user transceivers and
multiple filter-and-forward (FF) relays. The FF relaying technique along with the multi-carrier …

This paper deals with joint source and relay beamforming (BF) design for an amplify-and-
forward (AF) multiantenna multirelay network. Considering that the channel state information …

Multiple-input multiple-output (MIMO) relays can improve cell coverage and data throughput
for wireless networks. The key challenge for the success of MIMO relay networks is …

We consider a two-way relaying system employing physical layer network coding (PNC) in
channels suffering from frequency-selective fading. In order to mitigate the distortions …
