Binary Concentration Shift Keying Realization for Molecular Communication via Genetic Circuits

The growth of synthetic biology has encouraged the molecular communication (MC) community to design biological-inspired systems. Synthetic biology provides tools to control and engineer living organisms to yield chemical signals relative to electronics signal. In this paper, we propose a binary concentration shift keying (BCSK) system for MC using genetic circuits. We characterize our proposed system by separating the system into three building blocks: molecule propagation to an absorbing wall, gate cells processing, and molecule propagation to the counting receiver. The analytical analysis of our proposed BCSK design can be derived from the combination of the building blocks' impulse responses. We validate the analytical derivations and the performance of the BCSK through BSim simulations.
