This paper studies the wireless two-way relay channel (TWRC), where two source nodes, S1
and S2, exchange information through an assisting relay node, R. It is assumed that R …

It is becoming more important that next-generation wireless networks wisely integrate
multiple services at the physical layer to increase spectral efficiency. In this article, physical …

In this paper, we study an optimal transmit strategy for multiple-input single-output (MISO)
Gaussian channels with joint sum and per-antenna power constraints. We study in detail the …

Multi-way communication is a means to significantly improve the spectral efficiency of
wireless networks. For instance, in a bi-directional (or two-way) communication channel, two …

In this paper, we propose multiuser multiple-input multiple-ouput (MIMO) one-and two-way
relaying protocols. Several wireless MIMO node pairs are establishing either unidirectional …

This paper considers artificial noise (AN) aided transmit designs for multiuser MISO systems
in the eyes of service integration. Specifically, we combine two sorts of services, and serve …

A multiple-input multiple-output two-way relay channel consisting of two communication
nodes and a full-duplex relay node in which no direct link exists between the two …

In this work the transmit covariance matrix optimization problem for the discrete memoryless
MIMO Gaussian bidirectional broadcast channel is studied. A half-duplex relay node …

In this paper, we consider the relaying of orthogonal space-time block codes (OSTBCs) in a
two-way amplify-and-forward (AF) multiple-input-multiple-output (MIMO) relay system with …

We consider a three-node network where a relay node establishes a bidirectional
communication between the two other nodes using a spectrally efficient decode-and-forward …
