Towards Weight Distribution-Aware Polar Codes
Mohammad Rowshan, Vlad-Florin Dragoi
Polar codes are constructed based on the reliability of sub-channels resulting from the polarization effect. However, this information-theoretic construction approach leads to a po…

On Weight Enumeration and Structure Characterization of Polar Codes via Group Actions
Vlad-Florin Dragoi, Mohammad Rowshan
In this article, we provide a complete characterization of codewords in polar codes with weights less than twice the minimum distance, using the group action of the lower triangula…

PAC Codes Meet CRC-Polar Codes
Xinyi Gu, Mohammad Rowshan, Jinhong Yuan
CRC-Polar codes under SC list decoding are well-regarded for their competitive error performance. This paper examines these codes by focusing on minimum weight codewords, breaking…
