On the Concatenations of Polar Codes and Non-Binary LDPC Codes

IEEE Access, 2018
An interleaved concatenation scheme of polar codes with non-binary low-density parity check (NBLDPC) codes is proposed in this paper to improve the error-correcting performance of polar codes with finite code length. The information blocks of inner polar

A Low-Complexity Sorting Network for a Fast List Polar Decoder

IEEE Access, 2023
Fast list decoding algorithms for polar codes have been proposed to achieve low latency and high error correction performance. In the Rate-1 and SPC nodes of fast list decoding, a high-complexity sorter is required if multiple bits are to be decoded ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Efficient Sorting Architecture for List-Fast-SSC Decoding of Polar Codes

IEEE Access, 2018
Polar codes have been proven to achieve the symmetric capacity of memoryless channel. Compared with a successive cancellation list decoder, list-Fast simplified-successive cancellation generates more candidate paths, which leads to more resource costs ...

Error-Aware SCFlip Decoding of Polar Codes

IEEE Access, 2020
The successive-cancellation flip (SCFlip) decoder and its variants provide a significant coding gain with the average complexity practically identical to that of the successive cancellation (SC) decoder in a wide range of signal-to-noise ratios (SNRs ...

Establishing Shape Correspondences: A Survey

Computer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Complexity-Constrained D-SCFlip Decoding

IEEE Open Journal of the Communications Society
Dynamic successive cancellation flip (D-SCFlip) decoding has emerged as a low-complexity alternative to successive cancellation list (SCL) decoding for polar codes, bridging the performance gap between conventional successive cancellation (SC) and SCL ...

Seeing the Speaker's Face Enhances Second Language Shadowing: Neural and Behavioral Evidence

Language Learning, EarlyView.
Abstract This functional magnetic resonance imaging (fMRI) study investigated how facial cues influence second language (L2) shadowing among 42 Japanese learners of English. Participants completed four conditions that varied by task type (listening vs. shadowing) and visual input (face vs. mosaic).

Performance of an adaptive successive serial-parallel CDMA cancellation scheme in flat Rayleigh fading channels

, 2000
The performance of a successive concatenated cancellation scheme for code-division multiple-access (CDMA) uplink transmission in cellular mobile radio is presented. Both serial and parallel cancellation stages are employed.
