Influence of neighboring absorbing receivers upon the inter-symbol interference in a diffusion-based molecular communication system

A Diffusion-based Molecular Communication (DMC) system is based on the free diffusion of particles that carry the message between the transmitter and the receivers. One of the main problems which lead to decreased data rates in such network is the Inter Symbol Interference (ISI) caused by the heavy tail of the impulse response. In this paper, we study the influence of neighboring absorbing receivers upon the Inter Symbol Interference (ISI) of a Diffusion-based Molecular Communication (DMC) point-to-point link. It is shown that neighboring absorbing receivers have a noticeable impact on reducing the tail of the detected pulse-shape and, hence, higher achievable throughput are reachable.
