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.

On Path Memory in List Successive Cancellation Decoder of Polar Codes [PDF]
2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018 Polar code is a breakthrough in coding theory. Using list successive cancellation decoding with large list size L, polar codes can achieve excellent error correction performance. The L partial decoded vectors are stored in the path memory and updated according to the results of list management.

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.
