On Polar Coding with Feedback
Ling Liu, Qi Cao, Liping Li +1
In this work, we investigate the performance of polar codes with the assistance of feedback in communication systems. Although it is well known that feedback does not improve the c…
Decoding Golay Codes and their Related Lattices: A PAC Code Perspective
Yujun Ji, Ling Liu, Shanxiang Lyu +3
In this work, we propose a decoding method of Golay codes from the perspective of Polarization Adjusted Convolutional (PAC) codes. By invoking Forney's cubing construction of Golay…
Revisit the AWGN-goodness of Polar-like Lattices
Ling Liu, Junjiang Yu, Shanxiang Lyu +1
This paper aims to provide a comprehensive introduction to lattices constructed based on polar-like codes and demonstrate some of their key properties, such as AWGN goodness. We fi…
Construction of Simultaneously Good Polar Codes and Polar Lattices
Ling Liu, Ruimin Yuan, Shanxiang Lyu +2
In this work, we investigate the simultaneous goodness of polar codes and polar lattices. The simultaneous goodness of a lattice or a code means that it is optimal for both channel…
On the quantization goodness of polar lattices
Ling Liu, Shanxiang Lyu, Cong Ling +1
In this work, we prove that polar lattices, when tailored for lossy compression, are quantization-good in the sense that their normalized second moments approach a…
