Partially Information Coupled Duo-Binary Turbo Codes [PDF]
arXiv, 2020 Partially information coupled turbo codes (PIC-TCs) is a class of spatially coupled turbo codes that can approach the BEC capacity while keeping the encoding and decoding architectures of the underlying component codes unchanged. However, PIC-TCs have significant rate loss compared to its component rate-1/3 turbo code, and the rate loss increases with ...

Adaptive Turbo Equalization of Probabilistically Shaped Constellations [PDF]
arXiv, 2023 Fiber nonlinearity compensation of probabilistically shaped constellations with adaptive turbo equalization is investigated for the first time. Potential for more than 100% transmission reach extension is demonstrated by combining probabilistic shaping, single-channel digital backpropagation, and adaptive turbo equalization.

Frequency-Domain Turbo Equalisation in Coded SC-FDMA Systems: EXIT Chart Analysis and Performance [PDF]
, 2012 In this paper, we investigate the achievable performance of channel coded single-carrier frequency division multiple-access (SC-FDMA) systems employing various detection schemes, when communicating over frequency-selective fading channels.

Identification of compounds from chufa (Eleocharis dulcis) peels by widely targeted metabolomics
Food Science &Nutrition, Volume 11, Issue 1, Page 545-554, January 2023., 2023 The big Chinese water chestnut (BCWC) and small Chinese water chestnut (SCWC) peels using ultraperformance liquid chromatography/mass spectrometry (UPLC/MS)‐based metabolomics analysis. A total of 321 significant metabolites, including 90 flavonoids, 25 phenylpropanoids, and 33 organic acids and derivatives, were identified/annotated from BCWC and SCWC.

EXIT Chart Analysis of Turbo Compressed Sensing Using Message Passing De-Quantization [PDF]
, 2015 We propose an iterative decoding method, which we call turbo-CS, for the reception of concatenated source-channel encoded sparse signals transmitted over an AWGN channel. The turbo-CS encoder applies 1-bit compressed sensing as a source encoder concatenated serially with a convolutional channel encoder.

A Turbo Detection and Sphere-Packing-Modulation-Aided Space-Time Coding Scheme
, 2007 Arecently proposed space-time block-coding (STBC) signal-construction method that combines orthogonal design with sphere packing (SP), referred to here as STBC-SP, has shown useful performance improvements over Alamouti’s conventional orthogonal design ...

Near Capacity Irregular Turbo Code [PDF]
, 2016 The purpose of this study is to construct a near capacity Irregular Turbo Code and to evaluate its performance over Gaussian channel. The methodology used to evaluate and measure the performance of the new design is by simulating the system by developing a software platform using Matlab.

Epitope Mapping of Anti‐Neurofascin 155 Antibody in a Large Cohort of Autoimmune Nodopathy Patients
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Autoimmune nodopathy (AN), a newly recognized disease entity, is an immune‐mediated polyneuropathy involving autoantibodies against cell adhesion molecules located in nodes of Ranvier and paranodal regions, such as neurofascin 186 (NF186) and neurofascin 155 (NF155). The present study aimed to identify the epitopes for autoantibodies

A comparison of multiband and multiband multiecho gradient‐echo EPI for task fMRI at 3 T
Human Brain Mapping, Volume 44, Issue 1, Page 82-93, January 2023., 2023 In summary, we found that multiband multiecho (MBME) and MB give a comparable performance in most brain regions with this comparison study. In the regions with dropouts and susceptibility induced inhomogeneity, MBME performed somewhat better at the group level.
