Novel adaptive transmission algorithms for free-space optical links
(IEEE, 2012-12)
Atmospheric turbulence is a major degrading factor in free-space optical (FSO) systems. Since turbulence-induced fading results in a very slowly-varying channel, reliable feedback is possible allowing the implementation ...
Relay selection for cooperative underwater acoustic communication systems
(IEEE, 2012)
In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ...
Outage capacity regions of multicarrier DF relaying in underwater acoustic channels
(IEEE, 2012)
In this paper, we investigate the information theoretical limits on the performance of cooperative multicarrier underwater acoustic (UWA) communication systems. We assume decode-and-forward (DF) relaying and consider ...
Pricing for open access femtocell networks using market equilibrium and non-cooperative game
(IEEE, 2012)
In this paper, we address the pricing problem in open-access femtocell networks. We use economic and game theoretic approaches such as market equilibrium and non-cooperative game to propose novel pricing schemes. In our ...
Multi-hop relaying over the atmospheric poisson channel: outage analysis and optimization
(IEEE, 2012-03)
In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ...
Performance analysis of decode-and-forward multi-hop transmission for vehicular networks
(IEEE, 2012)
In this paper, we consider a multi-hop vehicular network in which the transmitted signal propagates through sequential vehicle hops to arrive to the destination vehicle. We assume doubly-selective channels and employ ...
Performance analysis of free space optical links over turbulence and misalignment induced fading channels
(IEEE, 2012)
The performance of free-space optical (FSO) communication system is investigated from the information theory perspective, under the influence of atmospheric loss and channel fading due to the turbulence and pointing error. ...
Performance of cooperative amplify-and-forward protocols in vehicular ad-hoc networks
(IEEE, 2012)
Cooperative diversity is a technique where the diversity associated with spatially distributed users is exploited to overcome violent fading in wireless channels. In vehicle-to-vehicle (V2V) communication systems, where ...
Outage performance and DMT analysis of DF parallel relaying in FSO IM/DD communications
(IEEE, 2012)
In this paper, we investigate the performance of cooperative diversity transmission in free-space optical (FSO) communications. We consider an FSO cooperative diversity system with a single decode-and-forward relay and a ...
Outage performance of FSO multi-hop parallel relaying
(IEEE, 2012)
In this paper, we investigate the outage performance of relay-assisted free-space optical (FSO) networks which build upon the combinations of serial and parallel relaying. We assume log-normal atmospheric turbulence channels ...
