Design of Rate-Compatible Polar Codes Based on Non-Uniform Channel Polarization

IEEE Access, 2021
In this article we propose a technique for polar codes (PC) construction for any code length. By default, PC construction is limited to code length proportional to the power of two.

AI Hallucinations in Tourism: How Errors Impact Consumer Trust and Recommendation Acceptance

Journal of Consumer Behaviour, EarlyView.
ABSTRACT Generative artificial intelligence (GenAI) is quickly transforming travel planning; however, its outputs can include hallucinations, which are plausible yet false statements that can undermine user judgement. Eliminating hallucinations in GenAI technology is currently impossible.

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.
