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 …

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 …

This paper presents theoretical characterizations and analysis for the physical layer of
multihop wireless communications channels. Four channel models are considered and …

In this paper; we propose a new cooperative communication protocol, which achieves
higher bandwidth efficiency while guaranteeing the same diversity order as that of the …

We consider a wireless network with one source/destination pair and several linear amplify-
and-forward relays. The influence of the gain allocation at the relays on the performance in …

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

We study selective digital relaying schemes where the relay may choose to retransmit or to
remain silent based on the qualities of the links between the source, relay and the …

This paper proposes a threshold-selection relaying scheme, in which each relay decides
whether to forward the source information by comparing the received signal power with a …

In this paper, we consider a simple network consisting of a source, a half-duplex decode-
and-forward relay, and a destination. In contrast to most of the existing literature, we assume …

This paper considers two-hop cooperative relaying using multiple relays and proposes a
threshold based relay selection protocol. In this protocol the relays are selected among …
