On Path Memory in List Successive Cancellation Decoder of Polar Codes [PDF]

open access: yes2018 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.

Joint Source-Channel Decoding of Polar Codes for Language-Based Source

open access: yes, 2016
We exploit the redundancy of the language-based source to help polar decoding. By judging the validity of decoded words in the decoded sequence with the help of a dictionary, the polar list decoder constantly detects erroneous paths after every few bits ...

Soft-Output Successive Cancellation List Decoding

open access: yesIEEE Transactions on Information Theory
We 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.

Design of Rate-Compatible Polar Codes Based on Non-Uniform Channel Polarization

open access: yesIEEE 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.

Achieving the Uniform Rate Region of General Multiple Access Channels by Polar Coding [PDF]

open access: yes, 2016
We consider the problem of polar coding for transmission over $m$-user multiple access channels. In the proposed scheme, all users encode their messages using a polar encoder, while a multi-user successive cancellation decoder is deployed at the receiver.
