DOI: 10.1109/lcomm.2016.2632727
Abstract: In terms of overall latency, one of the main bottlenecks of successive cancellation list (SCL) decoding of polar codes is the path pruning unit (PPU), whose goal is to prune $2L$ paths to $L$ paths.… read more here.

DOI: 10.1109/tcomm.2021.3064964
Abstract: Fast SC decoding overcomes the latency caused by the serial nature of the SC decoding by identifying new nodes in the upper levels of the SC decoding tree and implementing their fast parallel decoders. In… read more here.

DOI: 10.1109/tsp.2020.3020226
Abstract: List decoding of polar codes is an outstanding decoding method, in which a fixed-size list is applied to retain the most probable paths. In general, it is preferable to use a large-size list in the… read more here.

DOI: 10.1109/tvt.2020.3006369
Abstract: A reduced complexity sequential decoding algorithm for polar (sub) codes is described. The proposed approach relies on a decomposition of the polar (sub) code being decoded into a number of outer codes, and on-demand construction… read more here.
