Universal Construction for Polar Coded Modulation

IEEE Access, 2018
Recently, the polarization weight (PW), independent of transmission channel, is proposed to construct the polar codes based on the partial orders (POs) of the polarized bit channels (PBCs). In this paper, we propose a general PW (GPW) to solve the universal construction of the multilevel coding polar-coded modulation (MLC-PCM).

Low-Complexity Puncturing and Shortening of Polar Codes

, 2017
In this work, we address the low-complexity construction of shortened and punctured polar codes from a unified view. While several independent puncturing and shortening designs were attempted in the literature, our goal is a unique, low-complexity ...

Adaptive transmission construction based on polar codes

Journal of Physics: Conference Series, 2023
Abstract In actual communication scenarios, wireless transmission channels have the nature of heterogeneity. In order to ensure that data can be transmitted with high reliability and low delay, this paper designs a quasi-optimal polar code that can adapt to various channel environments, which called Q-polar code.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Cooperative Punctured Polar Coding (CPPC) Scheme Based on Plotkin’s Construction [PDF]

Radioengineering, 2016
A new cooperative punctured polar coding (CPPC) scheme with multi joint successive cancellation (MJSC) decoding at the destination is proposed, which may be obtained by applying puncturing algorithm to cooperative polar coding scenario.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Nonbinary Polar Codes Constructions Based on k-means Clustering

2021 International Conference on Information and Communication Technology Convergence (ICTC), 2021
Abstract This study investigates an efficient code construction method based on the Density evolution scheme, which has a component of channel merge routine. In this paper, k-means clustering algorithm is proposed for channel merging. By inspecting the merged channels, bit channels are ordered in estimated reliability.
