Fast Simplified Successive-Cancellation List Decoding of Polar Codes [PDF]

2017 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2017
Polar codes are capacity achieving error correcting codes that can be decoded through the successive-cancellation algorithm. To improve its error-correction performance, a list-based version called successive-cancellation list (SCL) has been proposed in the past, that however substantially increases the number of time-steps in the decoding process. The

Low Complexity List Decoding for Polar Codes with Multiple CRC Codes

Entropy, 2017
Polar codes are the first family of error correcting codes that provably achieve the capacity of symmetric binary-input discrete memoryless channels with low complexity.

CRC-Aided Logarithmic Stack Decoding of Polar Codes for Ultra Reliable Low Latency Communication in 3GPP New Radio

IEEE Access, 2019
This paper provides a detailed tutorial on the Cyclic Redundancy Check (CRC)-aided logarithmic successive cancellation stack (Log-SCS) algorithm. We apply these algorithms for the ultrareliable decoding of polar codes, which has relevance for the control

On the Concatenations of Polar Codes and Non-Binary LDPC Codes

IEEE Access, 2018
An interleaved concatenation scheme of polar codes with non-binary low-density parity check (NBLDPC) codes is proposed in this paper to improve the error-correcting performance of polar codes with finite code length. The information blocks of inner polar

Generalized Partially Information Coupled Polar Codes With Arbitrary Coupling Depth and Their Decoding Algorithms

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

An Enhanced Decoding Algorithm for Coded Compressed Sensing with Applications to Unsourced Random Access

Sensors, 2022
Unsourced random access (URA) has emerged as a pragmatic framework for next-generation distributed sensor networks. Within URA, concatenated coding structures are often employed to ensure that the central base station can accurately recover the set of ...

Successive cancellation list polar decoder using log-likelihood ratios [PDF]

2014 48th Asilomar Conference on Signals, Systems and Computers, 2014
Successive cancellation list (SCL) decoding algorithm is a powerful method that can help polar codes achieve excellent error-correcting performance. However, the current SCL algorithm and decoders are based on likelihood or log-likelihood forms, which render high hardware complexity. In this paper, we propose a log-likelihood-ratio (LLR)-based SCL (LLR-
