Complexity-Constrained D-SCFlip Decoding

IEEE Open Journal of the Communications Society
Dynamic successive cancellation flip (D-SCFlip) decoding has emerged as a low-complexity alternative to successive cancellation list (SCL) decoding for polar codes, bridging the performance gap between conventional successive cancellation (SC) and SCL ...

Code Analysis and Design for Successive Cancellation List Decoders

, 2022
The thesis investigates the potential of successive cancellation list (SCL) decoding for short-packet communications. First, SCL decoding is studied for transmission over binary-input memoryless symmetric channels. Codes are designed for specified decoding complexities that provide significant gains over the polar codes of the 5G standard.

Fully parallel low-density parity-check code-based polar decoder architecture for 5G wireless communications

ETRI Journal
A hardware architecture is presented to decode (N, K) polar codes based on a low-density parity-check code-like decoding method. By applying suitable pruning techniques to the dense graph of the polar code, the decoder architectures are optimized using ...
