On the Capacity of Diffusion Channels for Molecular Communication

Abstract

        In the present paper a diffusion channel for molecular communication is investigated. We assume that different amounts of particles are transmitted by an emitter, which diffuse through a medium and are partially absorbed by a receptor. This models biological information exchange, particularly in neural networks. We investigate the capacity of this channel. A novel general representation of mutual information is obtained. Lower and upper bounds for the capacity are derived and their accuracy is numerically assessed. Explicit results are achieved for the truncated Poisson channel, which is a prominent model for biological information exchange, however, notoriously hard to deal with.
