On the benefits of cooperation via power control in OFDM-based visible light communication systems
(IEEE, 2014)
In this paper, the performance of a visible light communication (VLC) network exploiting power control is considered. The achievable rate region of two VLC communication pairs is characterized. The system employs optical ...
Ray tracing based channel modeling for visible light communications
(IEEE, 2014)
Bu bildiride, Zemax 13 yazılımı aracılığı ile görünür ışık haberleşmesi (visible light communication, VLC) kanalları karakterize edilecektir. Yaklaşımımızda, ölçülerini tanımlayacağımız iç mekân ortamı üçboyutlu olarak ...
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 ...
Performance evaluation of multiple-bit delay detection with majority vote decision rule in optical DPSK systems
(IEEE, 2011)
In this paper, the performance of multiple-bit delay detection (MBDD) systems in optical differential phase shift keying (DPSK) is investigated. Assuming that the dominant noise in the system is originated by the optical ...
Performance analysis of cooperative diversity networks with imperfect channel estimation over Rician fading channels
(IEEE, 2010)
In this paper, we examine the effect of channel estimation error on the error and outage probabilities of a multi-relay system with amplify-and-forward relaying over frequency-flat Rician fading channel. We 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 ...
Practical implementation and performance study of a hard-switched hybrid FSO/RF link under controlled fog environment
(IEEE, 2014)
The availability and performance of terrestrial free-space optical (FSO) communication systems are heavily deterred by the fluctuating conditions of the atmospheric channel, particularly in the presence of visibility-limiting ...
