In this article we review an important class of wireless cooperation protocols known as
amplify-and-forward relaying. One or more low-complexity relay nodes assist the …

In this paper, we propose a relay selection amplify-and-forward (RS-AF) protocol in general
bidirectional relay networks with two sources and N relays. In the proposed scheme, the two …

Cooperative relaying recently emerged as a viable option for future wireless networks. By
simultaneously exploiting path loss savings known from relaying scenarios and the diversity …

We present the results from over-the-air experiments of a complete implementation of an
amplify and forward cooperative communications link. Our custom OFDM-based physical …

We consider various relaying strategies for wireless networks by comparatively examining
direct transmission, conventional relaying, and the novel concepts of cooperative relaying …

In this paper, we propose and analyze a simple protocol that simultaneously exploits two
potentials offered by wireless relay systems: diversity gains and pathloss savings. An …

In this letter, two common protocols in cooperative communications, namely one-way and
two-way amplify-andforward (AF) half-duplex relaying, are investigated and compared in …

We consider a multi-pair relay channel where multiple sources simultaneously communicate
with destinations using a relay. Each source or destination has only a single antenna, while …

We present a unified performance analysis of a system in which the source and the
destination are equipped with multiple antennas and communicating via a single antenna …

In this paper, we investigate the performance gain of hybrid decode-amplify-forward (HDAF)
relay protocol over the two conventional ones: the adaptive decode-forward (ADF) and …
