Least minimum symbol error rate based post-distortion for adaptive mobile VLC transmission with receiver selection
(Elsevier B.V., 2021-08)
In the context of beyond-5G indoor communication systems, visible light communication (VLC) has emerged as a viable supplement for existing RF-based systems and as an enabler for high datarate communications. However, the ...
A fractional-order transitional Butterworth-Butterworth filter and its experimental validation
(IEEE, 2021)
This paper introduces the generalization of the classical Transitional Butterworth-Butterworth Filter (TBBF) to the Fractional-Order (FO) domain. Stable rational approximants of the FO-TBBF are optimally realized. Several ...
Effect of scattering phase function on underwater visible light communication channel models
(Elsevier Ltd, 2021-10)
Non-sequential ray tracing simulations are commonly employed to model underwater visible light communication (VLC) channels. The accuracy of such simulations highly depends on how well the optical properties of water (i.e., ...
Low pass filter design with improved stop-band suppression and synthesis with transformer-free ladders
(John Wiley and Sons Inc, 2021-09)
A new method to design transformer-free low pass (LP) ladder network with improved stop-band suppression performance is introduced. The parametric representation of back-end impedance of LP filter network is established ...
Generic BER analysis of VLC channels impaired by 3D user-mobility and imperfect CSI
(Institute of Electrical and Electronics Engineers Inc., 2021-07)
Visible light communications (VLC) has emerged as a high-speed, low-cost, and green supplement for the existing radio frequency (RF) based infrastructures. However, the performance of VLC based systems is found to degrade ...
Channel modeling and characterization for VLC-based medical body sensor networks: trends and challenges
(IEEE, 2021-11-15)
Optical Wireless Communication (OWC) refers to transmission in unguided propagation media through the use of optical carriers, i.e., visible, Infrared (IR), and Ultraviolet (UV) bands. In this paper, we focus on indoor ...
A generalization of the Wiener-Hopf approach to direct and inverse scattering problems connected with non-homogeneous half-spaces bounded by n-part boundaries
(Oxford Univ Press, 2000-08)
The classical Wiener-Hopf method connected with mixed two-part boundary-value problems is generalized to cover n-part boundaries. To this end one starts from an ad-hoc representation for the Green function, which involves ...
Confluent edge conditions for the electromagnetic wave at the edge of a wedge bounded by material sheets
(Elsevier ScienceWave Motion, 2000-07)
The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges. In analytical studies they ...
Scattering of electromagnetic waves by a rectangular impedance cylinder
(Elsevier Science, 2000-04)
A uniformly valid asymptotic solution is developed for the diffraction of a high-frequency wave by an infinitely long rectangular cylinder having different impedance walls. The incident wave is generated by a line source ...
An immitance based tool for modelling passive one-port devices by means of darlington equivalents
(Urban & Fischer Verlag, 2001)
An immitance-based method is presented to model measured or computed data, obtained from a "passive one-port physical device" by means of its Darlington equivalent. In other words, the given data is modelled as a lossless ...
