A Chemical Reaction Network for Successive Interference Cancellation in Molecular Communication Networks

In this work, we conduct a preliminary evaluation of a chemical reaction network (CRN) realizing the successive interference cancellation (SIC) algorithm. SIC is a signal processing method used, for example, in non-orthogonal multiple access schemes. We present a CRN design with the sampled molecule concentration as the input and the detected bits as the output in a system with two transmitters and one receiver and evaluate its performance via stochastic simulations. This is a step towards realistically modeling SIC and possible effects on algorithm design in the chemical domain.
