In this paper, a novel non-uniform Binary Concentration Shift Keying (BCSK)modulation in the course of molecular communication is introduced. We considerthe nutrient limiting as the main reason for avoiding the nanotransmitters torelease huge number of molecules at once. The solution of this problem is inthe utilization of the BCSK modulation. In this scheme, nanotransmitterreleases the information molecules non-uniformly during the time slot. The3-dimensional diffusion channel with 3-dimensional drift is considered in thispaper. To boost the bit error rate (BER) performance, we consider arelay-assisted molecular communication via diffusion. Our computationsdemonstrate how the pulse shape of BCSK modulation affects the BER, and we alsoderive the energy consumption of non-uniform BCSK in the closed-formexpression. We study the parameters that can affect the BER performance, inparticular the distance between the nanotransmitter and the nanoreceiver, thedrift velocity of the medium, and the symbol duration. Furthermore, we proposean optimization problem that is designed to find the optimal symbol durationvalue that maximizes the number of successful received bits. The proposedalgorithm to solve the optimization problem is based on the bisection method.The analytical results show that non-uniform BCSK modulation outperformsuniform BCSK modulation in BER performance, when the aggregate energy is fixed.
