Order-Optimal Systematic Permutation Codes for Correcting t Deletions
Bolin Wu, Quan D. Bui, Kai Niu +2
This paper investigates the construction of full-systematic permutation codes capable of correcting multiple deletions under two complementary models, namely symbol-invariant delet…
Parallel Successive Cancellation Perturbation-Enhanced Decoding of Polar Codes via Offline Variance Design
Changwei Tu, Xuanyu Li, Kai Niu
Successive cancellation perturbation-enhanced (SCP) decoding improves the performance of finite-length polar codes by performing multiple SC decoding attempts with receiver-side pe…
Critical-Set-Aided Simplified Blind SCL Recognition of Polar Codes
Changwei Tu, Cheng Yang, Xianzhao Feng +1
Blind recognition of polar codes from noisy observations is a key problem in non-cooperative signal processing. Although existing blind successive cancellation list (BSCL) recognit…
A Hypothesis-Testing Analysis of Blind Recognition for Polar Codes
Changwei Tu, Cheng Yang, Xianzhao Feng +1
Blind recognition of polar-coded transmissions is an important task in non-cooperative wireless forensics and security-oriented signal analysis. When the code length is known or ha…
Blind Recognition of Polar Codes Using Successive Cancellation List Decoding
Changwei Tu, Yang Liu, Xianzhao Feng +1
Blind recognition of polar codes remains challenging in non-cooperative scenarios, particularly for information-set recognition with known code length. Existing methods mainly rely…
A Parity-Consistent Decomposition Method for the Weight Distribution of Pre-Transformed Polar Codes
Yang Liu, Bolin Wu, Yuxin Han +1
This paper introduces an efficient algorithm based on the Parity-Consistent Decomposition (PCD) method to determine the WD of pre-transformed polar codes. First, to address the bit…
