Reed-Muller Codes Polarize [PDF]
2019 IEEE 60th Annual Symposium on Foundations of Computer Science (FOCS), 2019 Reed-Muller (RM) codes and polar codes are generated by the same matrix $G_m= \bigl[\begin{smallmatrix}1 & 0 \\ 1 & 1 \\ \end{smallmatrix}\bigr]^{\otimes m}$ but using different subset of rows. RM codes select simply rows having largest weights.

Performance comparison of systematic polar code and non-systematic polar code
Tongxin xuebao, 2019 Polar code in channel coding schemes is a research hotspot in 5G communication field.Polar code is susceptible to error propagation under successive cancellation decoding,and the performance of the code at short and medium block lengths is not ideal.For ...

Concatenated LDPC-Polar Codes Decoding Through Belief Propagation
, 2017 Owing to their capacity-achieving performance and low encoding and decoding complexity, polar codes have drawn much research interests recently. Successive cancellation decoding (SCD) and belief propagation decoding (BPD) are two common approaches for ...

Belief Propagation Decoding of Polar Codes on Permuted Factor Graphs
, 2018 We show that the performance of iterative belief propagation (BP) decoding of polar codes can be enhanced by decoding over different carefully chosen factor graph realizations.

Achieving the Uniform Rate Region of General Multiple Access Channels by Polar Coding [PDF]
, 2016 We consider the problem of polar coding for transmission over $m$-user multiple access channels. In the proposed scheme, all users encode their messages using a polar encoder, while a multi-user successive cancellation decoder is deployed at the receiver.

A method for shorting of the system Polar code based on bit-reverse permutation
Dianxin kexue, 2019 Polar code,as a channel coding scheme in 3GPP standard,has good error correction performance.In order to further improve performance of the BER of the punctured Polar code,the shortening algorithm based on bit-reverse permuation was applied to the system

Simplified polar code decoding algorithm
Dianzi Jishu Yingyong, 2018 Polar code is an error correction coding technique, which can prove from the mathematical point of view to reach Shannon′s limit. However, the traditional decoding algorithm, such as the successive cancellation(SC) and the successive cancellation list ...

Hyperplane Neural Codes and the Polar Complex
, 2019 Hyperplane codes are a class of convex codes that arise as the output of a one layer feed-forward neural network. Here we establish several natural properties of stable hyperplane codes in terms of the {\it polar complex} of the code, a simplicial ...

Polar Codes for Broadcast Channels [PDF]
IEEE Transactions on Information Theory, 2013 Polar codes are introduced for discrete memoryless broadcast channels. For $m$-user deterministic broadcast channels, polarization is applied to map uniformly random message bits from $m$ independent messages to one codeword while satisfying broadcast constraints.
