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…
Beyond 1N Decoding: Capacity-Aware Rateless Polar Codes for IR-HARQ
Huazi Zhang, Xianbin Wang, Jiajie Tong +2
This paper introduces a novel framework for polar codes, designed for flexible Incremental Redundancy Hybrid Automatic Repeat Request (IR-HARQ). By generalizing the decoding order…
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…
Coded Water-Filling for Multi-User Interference Cancellation
Yuan Li, Zicheng Ye, Huazi Zhang +3
In this paper, we study the system-level advantages provided by rateless coding, early termination and power allocation strategy for multiple users distributed across multiple cell…
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…
Achieving the Fundamental Limit of Lossless Analog Compression via Polarization
Shuai Yuan, Liuquan Yao, Yuan Li +4
In this paper, we study the lossless analog compression for i.i.d. nonsingular signals via the polarization-based framework. We prove that for nonsingular source, the error probabi…
On the Message Passing Efficiency of Polar and Low-Density Parity-Check Decoders
Dawei Yin, Yuan Li, Xianbin Wang +8
This study focuses on the efficiency of message-passing-based decoding algorithms for polar and low-density parity-check (LDPC) codes. Both successive cancellation (SC) and belief…
