Turán-Theoretic Bounds on Several Elementary Trapping Sets in LDPC Codes
Ziyang Zhao, Haoran Xiong, Zicheng Ye +2
LDPC codes have attracted significant attention due to their capacity-approaching performance. Elementary trapping sets are the main cause of the error floor phenomenon in LDPC cod…
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…
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…
