The\nproposed framework is based on the Genetic Algorithm (GenAlg), where\npopulations (i.e., collections) of information sets evolve successively via\nevolutionary transformations based on their individual error-rate performance.\nThese populations converge towards an information set that fits the decoding\nbehavior. Using our proposed algorithm, we construct a polar code of length\n2048 with code rate 0.5, without the CRC-aid, tailored to plain successive\ncancellation list (SCL) decoding, achieving the same error-rate performance as\nthe CRC-aided SCL decoding, and leading to a coding gain of 1 dB at BER of\n$10^{-6}$. Further, a belief propagation (BP)-tailored polar code approaches\nthe SCL error-rate performance without any modifications in the decoding\nalgorithm itself.","url_abs":"http://arxiv.org/abs/1901.06444v1","url_pdf":"http://arxiv.org/pdf/1901.06444v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"genetic-algorithm-based-polar-code","repo_url":"https://github.com/AhmedElkelesh/Genetic-Algorithm-based-Polar-Code-Construction","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"2048","task_name":"Playing the Game of 2048"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
