ARUM: Polar Coded HARQ Scheme based on Incremental Channel Polarization
Kai Chen, Liangming Wu, Changlong Xu +3
A hybrid ARQ (HARQ) scheme for polar code, which is called active-bit relocation under masks (ARUM), is proposed. In each transmission, the data bits are encoded and bit-wisely XOR…
Polar Coding for Parallel Gaussian Channel
David Tse, Bin Li, Kai Chen
In this paper, we propose a Polar coding scheme for parallel Gaussian channels. The encoder knows the sum rate of the parallel channels but does not know the rate of any channel. B…
Rate-Compatible Punctured Polar Codes: Optimal Construction Based on Polar Spectra
Kai Niu, Jincheng Dai, Kai Chen +3
Polar codes are the first class of constructive channel codes achieving the symmetric capacity of the binary-input discrete memoryless channels. But the corresponding code length i…
Capacity-Achieving Rateless Polar Codes
Bin Li, David Tse, Kai Chen +1
A rateless coding scheme transmits incrementally more and more coded bits over an unknown channel until all the information bits are decoded reliably by the receiver. We propose a…
Reduce the Complexity of List Decoding of Polar Codes by Tree-Pruning
Kai Chen, Bin Li, Hui Shen +2
Polar codes under cyclic redundancy check aided successive cancellation list (CA-SCL) decoding can outperform the turbo codes and the LDPC codes when code lengths are configured to…
A Decision-Aided Parallel SC-List Decoder for Polar Codes
Bin Li, Hui Shen, Kai Chen
In this paper, we propose a decision-aided scheme for parallel SC-List decoding of polar codes. At the parallel SC-List decoder, each survival path is extended based on multiple in…
