Joint Source-Channel Decoding of Polar Codes for Language-Based Source
, 2016 We exploit the redundancy of the language-based source to help polar decoding. By judging the validity of decoded words in the decoded sequence with the help of a dictionary, the polar list decoder constantly detects erroneous paths after every few bits ...

Soft-Output Successive Cancellation List Decoding
IEEE Transactions on Information TheoryWe introduce an algorithm for approximating the codebook probability that is compatible with all successive cancellation (SC)-based decoding algorithms, including SC list (SCL) decoding. This approximation is based on an auxiliary distribution that mimics the dynamics of decoding algorithms with an SC decoding schedule.

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

Design of Rate-Compatible Polar Codes Based on Non-Uniform Channel Polarization
IEEE Access, 2021 In this article we propose a technique for polar codes (PC) construction for any code length. By default, PC construction is limited to code length proportional to the power of two.

A Split-Reduced Successive Cancellation List Decoder for Polar Codes
, 2015 This paper focuses on low complexity successive cancellation list (SCL) decoding of polar codes. In particular, using the fact that splitting may be unnecessary when the reliability of decoding the unfrozen bit is sufficiently high, a novel splitting ...

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

A Low-Complexity Sorting Network for a Fast List Polar Decoder
IEEE Access, 2023 Fast list decoding algorithms for polar codes have been proposed to achieve low latency and high error correction performance. In the Rate-1 and SPC nodes of fast list decoding, a high-complexity sorter is required if multiple bits are to be decoded ...
