Scalable Polar Code Construction for Successive Cancellation List Decoding: A Graph Neural Network-Based Approach

open access: yesIEEE Transactions on Communications, 2023
While constructing polar codes for successive-cancellation decoding can be implemented efficiently by sorting the bit-channels, finding optimal polar codes for cyclic-redundancy-check-aided successive-cancellation list (CA-SCL) decoding in an efficient ...

Polar Code Constructions Based on LLR Evolution

open access: yesIEEE Communications Letters, 2017
Polar code constructions based on mutual information or Bhattacharyya parameters of bit-channels are intended for hard-output successive cancellation (SC) decoders, and thus might not be well designed for use with other decoders, such as soft-output ...

Lossless source coding with polar codes

2010 IEEE International Symposium on Information Theory, 2010
In this paper lossless compression with polar codes is considered. A polar encoding algorithm is developed and a method to design the code and compute the average compression rate for finite lengths is given. It is shown that the scheme achieves the optimal compression rate asymptotically. Furthermore, the proposed scheme has a very good performance at

On the polar codes for MIMO

2013 International Conference on Wireless Communications and Signal Processing, 2013
Polarization, first introduced by Arikan, is a phenomenon that after some processing of a channel, the resulted channels are either almost clean channels or useless channels. In this paper we propose three schemes to polarize a MIMO channel and design the corresponding polar codes. In the first two schemes, the MIMO channel is decomposed into different
