Incremental diversity order for characterization of FSO communication systems over lognormal fading channels
(IEEE, 2020-04)
Free space optical (FSO) communication systems experience atmospheric turbulence-induced fading, which is typically modelled by lognormal distribution. Since the decreasing rate of error probability over lognormal fading ...
Pseudothermal light based quantum random number generator
(IEEE, 2020-10-22)
The importance of quantum random number generators (QRNGs) is increasing day by day. An important aspect of any QRNG is the speed of the system. This paper introduces the theory behind a pseudothermal light based QRNG. ...
Asymptotic performance of generalized transmit laser selection over lognormal turbulence channels
(IEEE, 2020-08)
In free space optical communication systems, transmit laser selection (TLS) has been proposed as an efficient fading-mitigation technique over turbulence channels. In TLS, the transmitter is equipped with a number of laser ...
Outage performance of mixed RF-FSO systems over DGG and nakagami-m channels
(IEEE, 2020-12)
In mixed RF (radio frequency)-FSO (free space optical) systems, the FSO link is used for backhauling while RF is used for wireless access. In many practical deployment scenarios especially in urban environments, more than ...
Experimental validation of a novel RLL code for visible light communication
(IEEE, 2020)
Flicker arising in visible light communication (VLC) system is typically mitigated by run-length-limited (RLL) codes. The IEEE 802.15.7 standard proposes RLL codes according to the modulation type and data rate. In this ...
Spatial power spectrum of natural water turbulence with any average temperature, salinity concentration, and light wavelength
(The Optical Society, 2020-10-01)
The power spectrum of water optical turbulence is shown to vary with its average temperature < T > and average salinity concentration < S >, as well as with light wavelength lambda. This study explores such variations for ...
Equivalent circuit for capacitive micromachined ultrasonic transducers to predict anti-resonances
(Springer Nature, 2020-12)
Equivalent circuit models have been long used to evaluate the dynamics of the capacitive micromachined ultrasonic transducer (CMUT). An important parameter in the characterization of a CMUT is the anti-resonance frequency, ...
Take the field from your smartphone: Leveraging UAVs for event filming
(IEEE, 2020-08-01)
This paper formulates the Sport Event Filming with Connectivity Constraints (SEF-C-2) problem. The SEF-C-2 problem is an event coverage problem, which exploits a team of Unmanned Aerial Vehicles (UAVs) over a limited field ...
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 ...
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 ...
