Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability
IEEE Access, 2019 A polar code with repeating bits (RB polar code), where a part of frozen bits only repeat their preceding information bits, is proposed. In the code construction, we propose cluster pairwise error probability (CPEP) to measure the competitiveness of the ...

Low Power, Area Efficient Architecture for Successive Cancellation Decoder
Emitter: International Journal of Engineering Technology, 2022 Polar codes have recently emerged as an error-correcting code and have become popular owing to their capacity-achieving nature. Polar code based communication system primarily consists of two parts, including Polar Encoder and Decoder.

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 ...

IEEE Access, 2021 We propose generalized partially information coupled (PIC) polar codes and their construction method. In the proposed codes, each code block (CB) shares systematic information bits partially with J adjacent CBs on each side, where J is referred to as the

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 ...

Polar Codes with exponentially small error at finite block length [PDF]
, 2018 We show that the entire class of polar codes (up to a natural necessary condition) converge to capacity at block lengths polynomial in the gap to capacity, while simultaneously achieving failure probabilities that are exponentially small in the block ...

Design of concatenated Hash-Polar code based on segmented CRC code
Dianxin kexue, 2022 As a linear block code, the polarization code has a lower coding complexity and a definite structure, but when it has a short or medium code length, the performance will be reduced.A design method of concatenated HashPolar codes based on segmented cyclic

CoRR, 2014 In this letter we propose a new hybrid code called "RM-Polar" codes. This new codes are constructed by combining the construction of Reed-Muller (RM) code and Polar code. It has much larger minimum Hamming distance than Polar codes, therefore it has much better error performance than Polar codes.

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.
