The amplify-and-forward (AF) relaying system considered here consists of a source node
with M transmit antennas, and relay and destination nodes with a single antenna each. The …

In this paper, we present closed form expressions for tight lower bounds of the performance
of dual-hop non-regenerative relaying over independent non-identical Weibull fading …

In this paper, we analyze the outage behavior of decode-and-forward (DF) relaying in the
context of selective two-way cooperative systems. First, a new relay selection metric is …

This paper presents a comparative performance analysis of multiuser multirelay two-way
and one-way amplify-and-forward relaying systems employing opportunistic transmission in …

Receive diversity with multiple amplify-and-forward (AF) relays is analyzed over unbalanced
hops with independent but not necessarily identically distributed Rayleigh fading. We …

This letter presents a study on the end-to-end performance of dual-hop wireless
communication systems equipped with nonregenerative fixed gain relays and operating …

This paper investigates the performance of a dual-hop amplify-and-forward relaying system
with co-channel interference at both the relay and destination nodes. The source node is …

Cooperative communications significantly improve the performance of wireless networks
with the help of relay nodes, whereas multiuser diversity (MUD) is a kind of diversity inherent …

In this paper, amplify-and-forward (AF)-based cooperation in a multiple-antenna-based
wireless communication system is studied. In particular, we address the problem of hop-by …

In this paper, we investigate the performance of a single-relay cooperative scenario where
the source, relay and destination terminals are equipped with multiple transmit/receive …
