Novel low-delay scheme for parallel Turbo decoding

Tongxin xuebao, 2011
In order to decrease decoding delay because of the iterative and recursive computation in MAP class algo-rithms,a novel parallel decoding scheme was proposed.The key of the novel scheme was to design a novel collision-free（CF） interleaver.After the ...

Evaluation of MMSE-Based Iterative Soft Detection Schemes for Coded Massive MIMO System

IEEE Access, 2019
There have been a number of researches on soft iterative detection and decoding scheme for coded multiple-input-multiple-output (MIMO) systems. Minimum mean square error (MMSE)-based detection schemes were often considered for massive MIMO systems, due ...

CPL‐Diff: A Diffusion Model for De Novo Design of Functional Peptide Sequences with Fixed Length

Advanced Science, EarlyView.
This study presents a diffusion model for generating functional peptide sequence lengths using mask control. The model can generate antimicrobial, antifungal, and antiviral peptides with specific lengths on demand. The model learns the structure of peptides better and generates peptides with better physicochemical properties, and the model has good ...

Tumor Microenvironment On‐A‐Chip and Single‐Cell Analysis Reveal Synergistic Stromal–Immune Crosstalk on Breast Cancer Progression

Advanced Science, EarlyView.
Using a 3D tumor microenvironment (TME)‐on‐a‐chip model, tumor–stromal–immune crosstalk in triple‐negative breast cancer is studied, revealing the TME's combinatorial effect on cancer progression. Integrating single‐cell transcriptomic analysis demonstrates metabolic reprogramming via the kynurenine pathway, highlighting the complex TME cellular ...

Neural Patterns of Social Pain in the Brain‐Wide Representations Across Social Contexts

Advanced Science, EarlyView.
Empathy arises from both physiological and social pain, yet their shared and context‐specific neural mechanisms remain unclear. Combining fMRI and multivariate pattern analysis, this study decodes overlapping empathy networks and distinct representations for social exclusion versus separation.

Face image de‐identification by feature space adversarial perturbation

Concurrency and Computation: Practice and Experience, Volume 35, Issue 5, 28 February 2023., 2023
Summary Privacy leakage in images attracts increasing concerns these days, as photos uploaded to large social platforms are usually not processed by proper privacy protection mechanisms. Moreover, with advanced artificial intelligence (AI) tools such as deep neural network (DNN), an adversary can detect people's identities and collect other sensitive ...

Low Complexity Approach for High Throughput Belief-Propagation based Decoding of LDPC Codes

Advances in Electrical and Computer Engineering, 2013
The paper proposes a low complexity belief propagation (BP) based decoding algorithm for LDPC codes. In spite of the iterative nature of the decoding process, the proposed algorithm provides both reduced complexity and increased BER performances as ...
