A Complexity Reduction Method for Successive Cancellation List Decoding [PDF]

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
This brief introduces a hardware complexity reduction method for successive cancellation list (SCL) decoders. Specifically, we propose to use a sorting scheme so that L paths with smallest path metrics are also sorted according to their path indexes for path pruning.

LLR-Based Successive Cancellation List Decoding of Polar Codes [PDF]

IEEE Transactions on Signal Processing, 2014
We show that successive cancellation list decoding can be formulated exclusively using log-likelihood ratios. In addition to numerical stability, the log-likelihood ratio based formulation has useful properties which simplify the sorting step involved in successive cancellation list decoding.

A New Specialized Node for Optimizing Decoding by Fast-Simplified Successive Cancellation of Polar Codes [PDF]

EPJ Web of Conferences
Error-correction codes ensure communication reliability, a critical requirement in modern wireless systems. Among these, polar codes, adopted in the fifth generation (5G) mobile network for channel control, achieve capacity via successive cancellation ...

Chained successive cancellation decoding of the extended Golay code [PDF]

2018 Iran Workshop on Communication and Information Theory (IWCIT), 2018
The extended Golay code is shown to be representable as a chained polar subcode. This enables its decoding with the successive cancellation algorithm and its stack generalization. The decoder can be further simplified by employing fast Hadamard transform. The complexity of the obtained algorithm is comparable with that of the Vardy algorithm.

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Multiple Folding for Successive Cancelation Decoding of Polar Codes

IEEE Wireless Communications Letters, 2014
Polar coding is known as the first provably capacity-achieving coding scheme under low-complexity suboptimal successive cancelation decoding (SCD). The large error-correction capability of finite-length polar codes is mostly achieved with relatively long codes.

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.
