DOI: 10.1007/s11265-018-1425-0

Abstract: 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… read more here.

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.
