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…

Adaptive Perturbation Enhanced SCL Decoder for Polar Codes
Xianbin Wang, Huazi Zhang, Jiajie Tong +2
For polar codes, successive cancellation list (SCL) decoding algorithm significantly improves finite-length performance compared to SC decoding. SCL-flip decoding can further enhan…
