Optimal Detection for Diffusion-Based Communications in the Presence of ISI
Communications based on diffusion refers to the transfer of information using molecules as message carriers whose propagation is governed by the laws of Brownian motion. Molecular communication is considered to be one of the most promising approaches for the end-to-end communication between nano-scale devices. In this paper, both an optimal and a suboptimal receiver detection scheme are proposed for a diffusion-based binary digital communication system in the presence of ISI. The transmission of binary information is accomplished by using On-Off Keying (OOK) with only one molecule.
