Initial efforts on wireless power transfer (WPT) have concentrated toward long-distance
transmission and high power applications. Nonetheless, the lower achievable transmission …

Energy efficiency in cellular networks is a growing concern for cellular operators to not only
maintain profitability, but also to reduce the overall environment effects. This emerging trend …

We develop and analyze low-complexity cooperative diversity protocols that combat fading
induced by multipath propagation in wireless networks. The underlying techniques exploit …

End-to-end performance of two-hop wireless communication systems with nonregenerative
relays over flat Rayleigh-fading channels is presented. This is accomplished by deriving and …

Cooperative diversity is a transmission technique, where multiple terminals pool their
resources to form a virtual antenna array that realizes spatial diversity gain in a distributed …

The integration of simultaneous wireless information and power transfer (SWIPT) and
cooperative relay (CoR) techniques has evolved as a new phenomenon for the next …

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 …

In this paper, we present relay-assisted transmission as a powerful fading mitigation tool for
free-space optical systems operating in atmospheric turbulence channels. We study both …

Motivated by the recent works on the relay channel and cooperative diversity, this letter
introduces coded cooperation, where cooperation is achieved through channel coding …

We consider three-node wireless relay channels in a Rayleigh-fading environment.
Assuming transmitter channel state information (CSI), we study upper bounds and lower …
