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…
On the Weight Spectrum of Rate-Compatible Polar Codes
Zicheng Ye, Yuan Li, Zhichao Liu +4
The weight spectrum plays a crucial role in the performance of error-correcting codes. Despite substantial theoretical exploration of polar codes with mother code length, a framewo…
Partial Orders in Rate-Matched Polar Codes
Zhichao Liu, Liuquan Yao, Yuan Li +4
In this paper, we establish the partial order (POs) for both the binary erasure channel (BEC) and the binary memoryless symmetric channel (BMSC) under any block rate-matched polar…
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…
