Enabling Fast Polar SC Decoding With IR-HARQ
IEEE Communications LettersTo extend the applications of polar codes within next-generation wireless communication systems, it is essential to incorporate support for Incremental Redundancy (IR) Hybrid Automatic Repeat Request (HARQ) schemes. For very high-throughput applications, Successive Cancellation (SC) decoding is particularly appealing for polar codes owing to its high ...

Sequential Polar Decoding with Cost Metric Threshold
Applied SciencesPolar codes have established themselves as a cornerstone in modern error correction coding due to their capacity-achieving properties and practical implementation advantages. However, decoding polar codes remains a computationally intensive task. In this

A Low-Complexity Ordered Statistics Decoding Algorithm for Short Polar Codes
Applied Sciences, 2019 In this paper, we propose a low-complexity ordered statistics decoding (OSD) algorithm called threshold-based OSD (TH-OSD) that uses a threshold on the discrepancy of the candidate codewords to speed up the decoding of short polar codes. To determine the

Belief Propagation With Permutated Graphs of Polar Codes
IEEE Access, 2020 The belief propagation (BP) decoding of polar codes provides better bit error rate (BER) and packet error rate (PER) performance than the successive cancelation (SC) decoding.

A Decision-Aided Parallel SC-List Decoder for Polar Codes
CoRR, 2015 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 information bits, therefore the number of split paths becomes very large and the sorting to find the top L paths becomes very complex.

Simplified Successive Cancellation Decoding of Polar Codes With Medium-Dimensional Binary Kernels
IEEE Access, 2018 A method is proposed, called l-formula, to design efficient successive cancellation (SC) decoding of polar codes with medium-dimensional binary kernels (dimensions up to 16).

An FPGA-based accelerator for rapid simulation of SC decoding of polar codes
2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS), 2015 In this paper we present an FPGA-based system for rapid frame error rate simulations of successive cancellation decoding of polar codes. Our system is implemented on a Xilinx Virtex-7 XC7VX485T FPGA and it supports polar codes of any rate and of blocklength up to N = 1024 bits on that device.

Improvement of Fast Simplified Successive-Cancellation Decoder for Polar Codes
Information, 2018 This paper presents a new latency reduction method for successive-cancellation (SC) decoding of polar codes that performs a frozen-bit checking on the rate-other (R-other) nodes of the Fast Simplified SC (Fast-SSC) pruning tree.

IEEE Access, 2018 Spatially coupled protograph (SC-P) low-density parity-check codes can achieve excellent performance and simple implementation when the coupling length is sufficiently large. However, in the case of small coupling lengths, terminated SC-P (TE-SC-P) codes
