Asymptotic MIMO Channel Model for Diffusive MC With Fully-Absorbing Receivers

This letter introduces an analytical model that gives the expected asymptotic cumulative number of molecules absorbed by each spherical receiver in a diffusive multiple-input multiple-output (MIMO) molecular communication (MC) system with pointwise transmitters. The reciprocal effect among fully absorbing (FA) receivers is taken into account using recently introduced concept fictitious negative source molecules. An agreement shown between proposed and numerical solution exact one from literature describing interaction receivers, which computed for sufficient long time.
