Outage performance of MIMO free-space optical systems in gamma-gamma fading channels
(IEEE, 2013)
In this paper, we consider a MIMO Free-Space Optical (FSO) communication system over gamma-gamma turbulence channels and derive a closed-form analytical expression for the outage probability taking into account the effects ...
A novel statistical model for turbulence-induced fading in free-space optical systems
(IEEE, 2013)
In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed Double GG distribution, is based ...
PHY layer performance evaluation of the IEEE 802.15.7 visible light communication standard
(IEEE, 2013)
The IEEE 802.15.7 standard defines a PHY layer and medium access control (MAC) layer for visible light communication and promises data rates sufficient to support audio and video multimedia services. In this paper, we first ...
MEMS based blood plasma viscosity sensor without electrical connections
(IEEE, 2013)
A MEMS based viscometer is reported. The device has a disposable cartridge and a reader. The cartridge contains microfluidic channels and a MEMS cantilever sensor. The reader contains the actuator and the readout optics ...
End-to-end performance of mixed RF/FSO transmission systems
(IEEE, 2013-11)
In this paper, we consider a heterogenous scenario where free-space optical (FSO) and radio-frequency (RF) technologies are deployed together as a dual-hop communication system, and we investigate the end-to-end outage ...
Multi-resampling doppler compensation in cooperative underwater OFDM systems
(IEEE, 2013)
We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ...
Outage performance and diversity gain analysis of free-space optical multi-hop parallel relaying
(IEEE, 2013-08)
In this paper, we investigate the outage performance of free-space optical mesh networks, which build upon the combination of serial (multi-hop) and parallel relaying. We assume log-normal atmospheric turbulence channels ...
Object tracking in the presence of occlusions using multiple cameras: a sensor network approach
( Association for Computing Machinery, 2013)
This article describes a sensor network approach to tracking a single object in the presence of static and moving occluders using a network of cameras. To conserve communication bandwidth and energy, we combine a task-driven ...
Capacity of practical wireless multihop broadcast networks
(Springer Science+Business Media, 2013-04)
In a wireless multihop broadcasting scenario, a number of relay nodes may cooperate the source node in order to improve the capacity of the network. However, the imposition of total energy and maximum hop constraints to ...
QCD sum rules for the coupling constants of vector mesons to octet baryons
(Springer Science+Business Media, 2013-05)
The QCD sum rules on the light cone proposed by Wang for the coupling constants of the ρ meson are generalized to the vector mesons ω and φ and all octet baryons, the Λ-hyperon included. A comparison with other results is given.
