BER Analysis of a Hybrid Modulation Scheme Based on PPM and MSK Subcarrier Intensity Modulation

IEEE Photonics Journal, 2015
In order to improve the bit-error-rate (BER) performance of free-space optical (FSO) communication systems employing binary phase-shift keying subcarrier intensity modulation (BPSK-SIM), an innovative hybrid modulation scheme called PPM-MSK-SIM is ...

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

ESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

Development of an improved acm scheme for mitigating earth-to-space propagation effects

Arid Zone Journal of Engineering, Technology and Environment, 2021
Satellite communication is a promising technology due to its ability to serve very large number of users with high data rate services. The communication link experiences propagation losses such as: Path loss, atmospheric losses, rain fading, ionosphere ...

Cancer therapy‐related cardiotoxicity is associated with distinct alterations of the myocardial lipidome

European Journal of Heart Failure, EarlyView.
Lipidome changes in anthracycline‐induced cardiotoxicity (AIC). Aims Anthracyclines are key components of various chemotherapy regimens, but their clinical utility is limited by severe cardiotoxic side effects. Previous studies have suggested that anthracycline‐induced cardiotoxicity (AIC) may be driven by alterations in myocardial lipid metabolism ...

On the general BER expression of one- and two-dimensional amplitude modulations

IEEE Transactions on Communications, 2002
Quadrature amplitude modulation (QAM) is an attractive technique to achieve high rate transmission without increasing the bandwidth. A great deal of attention has been devoted to the study of bit error rate (BER) performance of QAM, and approximate ...

Phosphanyl‐Substituted Tetrylenes and Ditetrelenes – Impact of Steric Bulk on Tetrylene/Ditetrelene Stability

European Journal of Inorganic Chemistry, Accepted Article.
Phosphorus‐substituted tetrylenes and ditetrelenes remain something of a rarity. The reaction between SnCl2 and two equivalents of (Dep2P)Li at low temperature gave the bis(phosphanyl)stannylene {(Dep)2P}2Sn (4Sn), although this compound decomposes in solution at room temperature (Dep = 2,6‐Et2C6H3).

Theoretical analysis of BER performance of nonlinearly amplified FBMC/OQAM and OFDM signals

EURASIP Journal on Advances in Signal Processing, 2014
In this paper, we introduce an analytical study of the impact of high-power amplifier (HPA) nonlinear distortion (NLD) on the bit error rate (BER) of multicarrier techniques.

Novel 3H ‐1,2,3‐Dithiaphosphole and Unprecedented 1,3,2,4‐Dithiadiphosphinane Heterocycles: Unanticipated Cyclization Reactions of Lawesson's Reagent and Alkynes

European Journal of Organic Chemistry, Accepted Article.
Treatment of Lawesson's reagent with selected alkyl or aryl alkynes results in the formation of cyclization products such as 3H‐1,2,3‐dithiaphosphole‐3‐sulfide or unprecedented 1,3,2,4dithiadiphosphinane‐2,4‐disulfide derivatives. The new heterocycles are characterized spectroscopically and in two cases by crystal structure analyses. Density functional
