Relay-assisted cooperative communications are a promising solution for error-performance
improvement and cell coverage extension. However, additional resources such as time slots …

In this paper, two cooperative communications schemes with inter-relay interference (IRI)
management are proposed for wireless multi-user decode-and-forward (DF) relay networks …

We consider a low mobility cellular relaying system downlink where two mobile users are
served by two neighboring decode-and-forward relays concurrently using the same …

In this paper, we present a multi-user cooperative protocol for wireless networks. Two
sources transmit simultaneously their information blocks and relays employ opportunistically …

Two-way relaying schemes in wireless systems obtain throughput gain by utilizing two
features (1) jointly serve two communication flows, thus implementing network coding and …

This paper considers multiple-input/multiple-output (MIMO) cooperative communication
systems with a decode-and-forward (DF) relay. We propose novel rate maximization …

We consider a heterogeneous wireless ad hoc network. All nodes are within radio range
and may employ an arbitrary number of antennas. Our goal is to achieve a distributed spatial …

Cooperative communications can achieve spatial diversity gain and enhance coverage.
However, conventional half-duplex relaying schemes suffer from the loss in spectral …
