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…
