Interference Alignment Using Reaction in Molecular Interference Channels

Interference alignment (IA) is a promising scheme to increase the throughput of the system with shared mediums. In this paper, we propose a novel IA scheme in molecular interference channels (IFCs) based on the choice of releasing/sampling times. To cancel the aligned interference signals and reduce the signal dependent noise, we use molecular reaction in the proposed IA scheme. We obtain the feasible region for the releasing/sampling times in the IA scheme using reaction. Further, we investigate the error performance of the proposed scheme. Our results show that the proposed IA scheme using reaction improves the performance significantly.
