# Polar Codes for Channels with Insertions, Deletions, and Substitutions

@article{Pfister2021PolarCF, title={Polar Codes for Channels with Insertions, Deletions, and Substitutions}, author={Henry D. Pfister and Ido Tal}, journal={2021 IEEE International Symposium on Information Theory (ISIT)}, year={2021}, pages={2554-2559} }

This paper presents a coding scheme for an insertion deletion substitution channel. We extend a previous scheme for the deletion channel where polar codes are modified by adding “guard bands” between segments. In the new scheme, each guard band is comprised of a middle segment of ‘1’ symbols, and left and right segments of ‘0’ symbols. Our coding scheme allows for a regular hidden-Markov input distribution, and achieves the information rate between the input and corresponding output of such a… Expand

This paper presents an implementation of low-complexity polar SC decoder for deletion channels, and proves polarization theorems for the polar bit-channels in presence of deletions when $d$ = o(n), which implies that the coding scheme is capable of achieving the symmetric information rate for this concatenated scheme with diminishing error probabilities as $n$ becomes large.
