Reliability-Dependent Scaling Laws of Deterministic Identification over Binary Symmetric Channels
Zhicheng Liu, Liuquan Yao, Guiying Yan +2
In this paper, we study the asymptotic behavior of deterministic identification (DID) over binary symmetric channels (BSCs) under vanishing error constraints. By introducing a mini…
Perturbation Power Selection for First-Error Delay Maximization in Enhanced SC Decoding
Zhicheng Liu, Liuquan Yao, Shuai Yuan +5
In this paper, we analyze the effect of perturbation power in delaying the first error position, i.e., the first information bit incorrectly decoded by the successive cancellation…
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…
The Impact of the Distance Between Cycles on Elementary Trapping Sets
Haoran Xiong, Guanghui Wang, Zhiming Ma +1
Elementary trapping sets (ETSs) are the main culprits of the performance of low-density parity-check (LDPC) codes in the error floor region. Due to their large quantities and compl…
On the lifting degree of girth-8 QC-LDPC codes
Haoran Xiong, Guanghui Wang, Zhiming Ma +1
The lifting degree and the deterministic construction of quasi-cyclic low-density parity-check (QC-LDPC) codes have been extensively studied, with many construction methods in the…
