Abstract

As the nanotechnology becomes more and more mature, the concept of molecular communication emerged and attracted lots of researchers’ attention. The most widespread model for a molecular communication channel is the diffusion-based channel, where the information-carrying molecules propagate randomly in the medium based on Brownian motion. As for multi-input multi-output (MIMO) transmissions, there are not only inter-symbol interference (ISI), some molecules may arrive at the receiver after their intended time-slot, as interference. Another source of interference is the inter-link interference (ILI), which emerges when receiver receive other transmitters’ molecules. In this paper, we study the bit error rate (BER) performance of a molecular communications system having two transmitters and two receiver with two receptors by considering ISI and ILI. Last, dual threshold algorithm is proposed to optimize the system BER.
