Experimental investigation on the effect of wavelength on aperture averaging in FSO communications
(The Optical Society, 2020-06-01)
Atmospheric turbulence is a major impairment in free-space optical (FSO) communication systems. Based on the fact that the size of receiver aperture is much larger than operation wavelength, aperture averaging extracts ...
A simulation study of cooperative underwater acoustic communication
(2012-08)
Cooperative communication promises significant performance gains in terms of link reliability, spectral efficiency, system capacity, and transmission range. Due to its indisputable advantages for high-speed underwater ...
Mixture-kernel based post-distortion in RKHS for time-varying VLC channels
(IEEE, 2019-02)
Visible light communication (VLC) based systems are a viable green supplement to existing radio frequency based communication systems. However, it has been found that the performance of VLC based systems is impaired in ...
Multi-pick round robin arbiter
(2012-08)
In this thesis, we propose two multi(m)-pick Round Robin Arbiter (RRA) architectures. An m-pick RRA selects the m topmost requests out of n inputs with priority order indicated by an internally kept pointer (with an update ...
Optimal relay placement and diversity analysis of relay-assisted free-space optical communication systems
(IEEE, 2013-01)
Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ...
On the performance analysis of multirelay cooperative diversity systems with channel estimation errors
(IEEE, 2011-06)
In this paper, we investigate the performance of an amplify-and-forward (AF) cooperative diversity system with multiple relays in the presence of channel estimation errors. We consider both conventional relaying (in which ...
Cooperative underwater acoustic communications
(IEEE, 2013-07)
This article presents a contemporary overview of underwater acoustic communication (UWAC) and investigates physical layer aspects on cooperative transmission techniques for future UWAC systems. Taking advantage of the ...
Generating fast logic circuits for m-select n-port round Robin arbitration
(IEEE, 2013)
This paper generalizes the problem of Round Robin Arbitration (RRA) from 1-select to m-select (mRRA) and offers new circuit architectures for it. RRAs are found in networking equipment and computer systems with high ...
Investigating voice as a biomarker: Deep phenotyping methods for early detection of Parkinson's disease
(Elsevier, 2020-04)
Voice technology has grown tremendously in recent years and using voice as a biomarker has also been gaining evidence. We demonstrate the potential of voice in serving as a deep phenotype for Parkinson's Disease (PD), the ...
Capacity analysis of free space optical links for a partially coherent gaussian beam over a turbulent channel with pointing errors
(IEEE, 2013)
In this paper, we investigate the joint effects of
beam width and the spatial coherence length in a partially coherent free-space optical (FSO) link from the information theory perspective, taking into account the combined ...
