A novel concentration-type based modulation in molecular communication

Major problems in diffusion based molecular communication are inter symbol interference (ISI) and low data rates. Keeping symbol duration as long as possible may be a solution, but this leads to even further reduced data rates. In this paper, a novel modulation system that works well in higher data rates is proposed by combining other proposed techniques in the literature. This system relies on encoding the information into addition of different types of molecules and majority molecule type in this summation. Simulation results show that, the proposed method outperforms the previous approaches in the literature for higher data rates.
