An Adaptive Ordered Shifted-Pruning List Decoder for Polar Codes
IEEE Access, 2020 The polar code has been selected as a channel coding solution for the control channel of 5th generation wireless systems (5G). Compared with the conventional cyclic-redundancy-check-aided successive cancellation list (CA-SCL) decoder for polar codes, the

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

Segmented Successive Cancellation List Polar Decoding with Tailored CRC [PDF]
Journal of Signal Processing Systems, 2019 As the first error correction codes provably achieving the symmetric capacity of binary-input discrete memory-less channels (B-DMCs), polar codes have been recently chosen by 3GPP for eMBB control channel. Among existing algorithms, CRC-aided successive cancellation list (CA-SCL) decoding is favorable due to its good performance, where CRC is placed at

Belief Propagation Decoder With Multiple Bit-Flipping Sets and Stopping Criteria for Polar Codes
IEEE Access, 2020 Compared with successive cancellation list (SCL) decoders, belief propagation (BP)-based decoders suffer performance loss in middle-and high-signal-to-noise ratio (SNR) regions.

Enhanced Adaptive Successive-Cancellation List Decoder
Journal of Physics: Conference Series, 2020 Abstract Adaptive successive cancellation list decoder (ASCLD) with upsizing scheme as a well-known approach can significantly reduce the average list size of SCL algorithm for polar codes with cyclic redundancy check (CRC). Since it needs to re-decode the whole received bits if no survival path verifies CRC, it dramatically increases ...

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.

Successive-Cancellation Flip Decoding of Polar Codes with a Simplified Restart Mechanism [PDF]
, 2023 Polar codes are a class of error-correcting codes that provably achieve the capacity of practical channels. The successive-cancellation flip (SCF) decoder is a low-complexity decoder that was proposed to improve the performance of the successive ...
