A Path-Survival Analytical Framework for SCL Decoding of Polar Codes
Xianbin Wang, Zhichao Liu, Yuan Li +4
A theoretical analysis of CRC-aided successive cancellation list (CA-SCL) decoding for polar codes remains an open problem, despite its widespread practical adoption. While low-den…

Stitched Polar Codes
Yuan Li, Zicheng Ye, Huazi Zhang +4
In this paper, we introduce stitched polar codes, a novel generalization of Arıkan's regular polar codes. Our core methodology reconfigures the fundamental polarization process by…
