Performance Assessment of OFDM System using Reed-Solomon Codes over Fading Channels

open access: yesJournal of Electrical, Electronics and Informatics, 2018
This paper study the performance of Orthogonal Frequency Division Multiplexing (OFDM) system over AWGN and Rayleigh fading channels. OFDM performs multi-carrier transmission where all the subcarriers are orthogonal to each other.

Buyers' response to third‐party quality certification: Theory and evidence from Ethiopian wheat traders

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract When quality attributes of a product are not directly observable, third‐party certification (TPC) enables buyers to distinguish between quality levels and reward sellers accordingly. We study the adoption of TPC by traders in smallholder‐based agricultural value chains in low‐income countries, where traders aggregate products from many small ...

On Determining Deep Holes of Generalized Reed-Solomon Codes

open access: yes, 2013
For a linear code, deep holes are defined to be vectors that are further away from codewords than all other vectors. The problem of deciding whether a received word is a deep hole for generalized Reed-Solomon codes is proved to be co-NP-complete. For the

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): baseline data from day surgery practice in the UK

open access: yesAnaesthesia, EarlyView.
Summary Introduction Most patients undergoing elective surgery in the UK are discharged from hospital on the same day. Despite this, there is a lack of UK patient‐centred outcome measures relating to quality of recovery, pain and analgesic use. The POPPY study was a UK‐wide prospective, observational study measuring short‐ and longer‐term patient ...

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): chronic post‐surgical pain prevalence and associations*

open access: yesAnaesthesia, EarlyView.
Summary Introduction Day‐case surgical activity is increasing in the UK yet there is a lack of data on the prevalence of chronic post‐surgical pain in this population. This study uses data from the POPPY study to estimate the prevalence of chronic post‐surgical pain after day‐case surgery, its relationship with quality of life and also explores ...

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

100 Gb/s Data Link Layer - from a Simulation to FPGA Implementation

open access: yesJournal of Telecommunications and Information Technology, 2016
In this paper, a simulation and hardware implementation of a data link layer for 100 Gb/s terahertz wireless communications is presented. In this solution the overhead of protocols and coding should be reduced to a minimum.

Distributed Reed-Solomon Coded Cooperative Space-Time Labeling Diversity Network [PDF]

open access: yesRadioengineering, 2022
This paper proposes a distributed Reed-Solomon coded cooperative labeling diversity (DRSCC-LD) scheme over the Rayleigh frequency-flat fast fading channel to further improve the BER performance. The non-binary Reed-Solomon (RS) code with more consecutive

Error correction by Reed–Solomon codes using its automorphisms

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2021
The article explores the syndrome invariants of АГ-group of automorphisms of Reed–Solomon codes (RS-codes) that are a joint group of affine and cyclic permutations. The found real invariants are a set of norms of N Г-orbits that make up one or another АГ-

Using Recontextualisation Theory to Understand Learning Across Multiple Sites in Simulation‐Based Nurse Education

open access: yesJournal of Advanced Nursing, EarlyView.
ABSTRACT Aim The aim of this discussion paper is to explore whether recontextualisation theory deepens our understanding of learning across multiple sites when introducing simulation‐based education (SBE) into nurse education. Background The requirement for students to learn in clinical placements remains an aspiration as well as a regulatory ...
