On the Capacity of Point-to-Point and Multiple-Access Molecular Communications With Ligand-Receptors

摘要: In this paper, we consider bacterial point-to-point and multiple-access molecular communications with ligand-receptors. For communication, investigate common signaling methods, namely, the level scenario, in which information is encoded into multiple concentration levels of a single molecule type, type bits are types each level. We tradeoffs two scenarios terms capacity. derive an upper bound on capacity using Binomial channel model symmetrized Kullback–Leibler divergence. A lower also derived when environmental noise negligible. blocking effect receptor by different type. Finally, study communications, for three based types: 1) same labeling types; 2) 3) types. total inner bounds region these
