Error control for calcium signaling based molecular communication

Calcium signaling is one of the most widely studied means of providing communication for molecular communications in nanonetworks. In this paper, we investigate error control approaches for calcium signaling based molecular communications. Taking an information theoretic approach we show, using a stochastic simulation model, how error conditions such as signal fading, multipath propagation and spatial noise can affect the communication reliability. In order to counter these issues, we proposed using baseband modulations techniques (Return-to-zero (RZ) and Non-return-to-zero (NRZ)) in combination with channel coding (Reed Solomon) to improve the performance of the communication system.
