Perspective method for reconfigurable intelligent surface design for NOMA transmission: Theoretical study

open access: yesFrontiers in Communications and Networks, 2023
The method (paradigm) presented here was inspired by two basic ideas: the assumption of the MIMO-RIS-NOMA communication channel as a dispersive channel with fading, and the representation of the latter by means of the generalized Kronecker channel model (

Recent Developments in Laser Fading of Denim: A Critical Review

open access: yesJournal of Natural Fibers, 2022
The utilization of denim dates back to ancient times, and still, it is one of the most utilized fabrics around the globe. Special considerations are given to its fading effects. There are many ways for the said fading associated with pros and cons.

Frame delay and loss analysis for video transmission over time-correlated 802.11A/G channels [PDF]

open access: yes, 2007
This paper presents simulation results for the transmission of unicast MAC frames over 802.11a/g. Fading channel models at various Doppler frequencies are developed to generate time- correlated SNR waveforms.

Rayleigh Fading Suppression in One-Dimensional Optical Scatters

open access: yesIEEE Access, 2019
A highly coherent wave is favorable for applications in which phase retrieval is necessary, yet a high-coherence wave is prone to encounter Rayleigh fading phenomenon as it passes through a medium of random scatters.

The Fluctuating Two-Ray Fading Model for mmWave Communications [PDF]

open access: yes, 2016
We introduce the Fluctuating Two-Ray (FTR) fading model, a new statistical channel model that consists of two fluctuating specular components with random phases plus a diffuse component.

Methodology for Estimating Communication Reliability in Shortwave Radio-Frequency Transmission Channels with Rician Fading Given Ionospheric Diffusivity

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2022
Introduction. There exists a technique for estimating the dependence of communication reliability in a shortwave radio-frequency transmission channel (SWRC) with a single discrete beam and diffuse wave scattering across small-scale ionospheric ...

Modeling of linear fading memory systems [PDF]

open access: yes, 1996
Motivated by questions of approximate modeling and identification, we consider various classes of linear time-varying bounded-input-bounded output (BIBO) stable fading memory systems and the characterizations are proved.

Statistical properties for multipath-relayed communications over fading channels [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
In this paper, a multipath transmission with no regenerative relays over fading channels has been addressed. The probability density function of minimum amplitude at relay stations input has been determined.
