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 ...
Energy sensing strategy optimization for opportunistic spectrum access
(IEEE, 2012-06)
This paper introduces a correlator-based energy sensing strategy for opportunistic spectrum access in a slow, flat-fading channel. The correlator provides weighted energy accumulation in time. We assume that the noise ...
Fast two-pick n2n round-robin arbiter circuit
(IEEE, 2012-06)
A regular (one-pick) round-robin arbiter circuit picks one active requester (if any) out of n requesters. A two-pick round-robin arbiter selects up to two requesters. An n2n two-pick round-robin arbiter indicates the picked ...
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 ...
