For a reliable transmission, not only good channel estimation and equalization, but also strong error correcting codes are needed. In this paper, we present the results of the coding competition “Wanted: Best channel codes for short underwater messages” as well as our own findings on the influence of the modulation alphabet size in the example of non-binary polar codes. Furthermore, the proposals of the competition are compared to other commonly used channel codes.en2078-248920202Multidisciplinary Digital Publishing Institutehttps://creativecommons.org/licenses/by/4.0/channel codingunderwater acoustic sensor networkforward error correctionphaseshift keyingpolar codeInformatikHandel, Kommunikation, VerkehrTechnikIngenieurwissenschaftenJournal Article2020-01-2310.15480/882.259510.3390/info1102005810.15480/882.2595Journal Article
