Belief-selective Propagation Detection for MIMO Systems
Wenyue Zhou, Yifei Shen, Liping Li +3
Compared to the linear MIMO detectors, the Belief Propagation (BP) detector has shown greater capabilities in achieving near optimal performance and better nature to iteratively co…
Polar Codes with Memory
Wenyue Zhou, Qiang Liu, Yifei Shen +4
Polar codes with memory (PCM) are proposed in this paper: a pair of consecutive code blocks containing a controlled number of mutual information bits. The shared mutual information…
Optimal Puncturing of Polar Codes With a Fixed Information Set
Liping Li, Wei Song, Kai Niu
For a given polar code construction, the existing literature on puncturing for polar codes focuses in finding the optimal puncturing pattern, and then re-selecting the information…
A General Construction and Encoder Implementation of Polar Codes
Wei Song, Yifei Shen, Liping Li +2
Similar to existing codes, puncturing and shortening are two general ways to obtain an arbitrary code length and code rate for polar codes. When some of the coded bits are puncture…
Segmented Successive Cancellation List Polar Decoding with Tailored CRC
Huayi Zhou, Xiao Liang, Liping Li +3
As the first error correction codes provably achieving the symmetric capacity of binary-input discrete memory-less channels (B-DMCs), polar codes have been recently chosen by 3GPP…
Channel Estimation with Systematic Polar Codes
Liping Li, Zuzheng Xu, Yanjun Hu
Study of polar codes in fading channels is of great importance when applying polar codes in wireless communications. Channel estimation is a fundamental step for communication to b…
A Correlation-Breaking Interleaving of Polar Codes in Concatenated Systems
Ya Meng, Liping Li, Chuan Zhang
It is known that the bit errors of polar codes with successive cancellation (SC) decoding are coupled. However, existing concatenation schemes of polar codes with other error corre…
Efficient Construction of Polar Codes
Wei Wang, Liping Li
The construction of polar codes for channels other than BECs requires sorting of all bit channels and then selecting the best of them for a block length . In this paper,…
A Novel Interleaving Scheme for Polar Codes
Ya Meng, Liping Li, Yanjun Hu
It's known that the bit errors of polar codes with successive cancellation (SC) decoding are coupled. We call the coupled information bits the correlated bits. In this paper, conca…
On the Polar Code Encoding in Fading Channels
Rui Deng, Liping Li, Yanjun Hu
Besides the determined construction of polar codes in BEC channels, different construction techniques have been proposed for AWGN channels. The current state-of-the-art algorithm s…
On the Symmetry of Polar Codes for Symmetric Binary-Input Discrete Memoryless Channels
Qiming Wang, Liping Li
In this paper, we study the symmetry of polar codes on symmetric binary-input discrete memoryless channels (B-DMC). The symmetry property of polar codes is originally pointed out i…
On the Error Performance of Systematic Polar Codes
Liping Li, Wenyi Zhang, Yanjun Hu
Systematic polar codes are shown to outperform non-systematic polar codes in terms of the bit-error-rate (BER) performance. However theoretically the mechanism behind the better pe…
