Polar Coding with Chemical Reaction Networks for Molecular Communications


In this paper, we propose a new polar coding scheme with molecular programming, which is capable of highly parallel implementation at a nano-scale without the need for electrical power sources. We designed chemical reaction networks (CRN) to employ either successive cancellation (SC) or maximumlikelihood (ML) decoding schemes for short polar codes. From differential equation analysis of the proposed CRNs, we demonstrate that SC and ML decoding achieve accurate computations across fully-parallel chemical reactions. In terms of the number of required chemical reactions, we verify the superiority of ML decoding over SC decoding for very short block lengths
