We introduce a new achievability scheme, termed opportunistic network decoupling (OND),
where a novel relay scheduling strategy is utilized in the K× N× K channel with interfering …

This paper deals with the problem of cooperative communication for a network with multiple
halfduplex relays. Two half-duplex relaying protocols, ie simultaneous and successive …

In this paper, we consider a distributed MIMO communication network in which multiple
transmitters cooperatively send common messages to a single receiver. In this scenario, it is …

Relays are being deployed in both fourth generation cellular systems and wide metropolitan
area networks in order to increase coverage and spectral efficiency. In this article, we …

In dieser Arbeit betrachten wir ein drahtloses Relaisnetzwerk, bei dem eine Halbduplex-
Mehrantennen-Relaisstation (RS) mehrere Kommunikationsgruppen unterstützt. Jede …

Early works on the capacity of the wireless relay channel date back more than 30 years. In
its genuine version this channel consists of three nodes: a source transmits data to a …

Diamond relay network is a kind of efficient cooperative network, in which the source user
selects two neighbors as relays and cooperates with both of them. In our previous work, we …

One of the key technologies in next generation systems for achieving high throughput and
providing better coverage is relaying. Relaying has attracted a high level of recent research …

In this paper, we consider a parallel relay network where two relays cooperatively help a
source transmit its message to a destination. We assume the source and the destination …

In this paper, protocols for the half-duplex relay channel are introduced and performance
limits are analyzed. Relay nodes underly an orthogonality constraint, which prohibits …
