Polar Decoding Tree Pruning Based on Soft Output Extraction
Li Shen, Yongpeng Wu, Wenjun Zhang
Although the successive cancellation list (SCL) decoding of polar codes exhibits excellent performance, it retains many decoding paths in the list with negligible contribution to t…
Probabilistic Shaped Multilevel Polar Coding for Wiretap Channel
Li Shen, Yongpeng Wu, Peihong Yuan +3
A wiretap channel is served as the fundamental model of physical layer security techniques, where the secrecy capacity of the Gaussian wiretap channel is proven to be achieved by G…
Soft-Output Fast Successive-Cancellation List Decoder for Polar Codes
Li Shen, Yongpeng Wu, Yin Xu +3
The soft-output successive cancellation list (SOSCL) decoder provides a methodology for estimating the a-posteriori probability log-likelihood ratios by only leveraging the convent…
GLDPC-PC Codes: Channel Coding Towards 6G Communications
Li Shen, Yongpeng Wu, Yin Xu +3
The sixth generation (6G) wireless communication system will improve the key technical indicators by one to two orders of magnitude, and come with some new features. As a crucial t…
Symbol-wise Puncturing for HARQ Integration with Probabilistic Amplitude Shaping
Li Shen, Yongpeng Wu, Derrick Wing Kwan Ng +2
In this letter, we propose a symbol-wise puncturing scheme to support hybrid automatic repeat request (HARQ) integrated probabilistic amplitude shaping (PAS). To prevent the probab…
MIMO Transmission Under Discrete Input Signal Constraints
Jie Feng, Biqian Feng, Yongpeng Wu +2
In this paper, we propose a multiple-input multipleoutput (MIMO) transmission strategy that is closer to the Shannon limit than the existing strategies. Different from most existin…
