A Generalized Strength-Based Signal Detection Model for Concentration-Encoded Molecular Communication

In this paper, a generalized strength-based signal detection model for Concentration-Encoded Molecular Communication (CEMC) has been presented. The generalized strength-based signal detection problem in diffusion-based CEMC system has been investigated in the presence of both diffusion noise and intersymbol interference (ISI). Amplitude-shift keying (ASK)modulated CEMC system has been considered with impulsive transmission scheme. The receiver for optimum signal detection has been developed theoretically and explained with both analytical and simulation results of binary signal detection. It is found that the receiver thus developed can detect the CEMC symbols; however, the performance of the receiver is influenced by two main factors, namely, communication range and transmission data rate. Correspondingly, the bit error rate (BER) performance of the receiver thus developed is further evaluated under various communication ranges and transmission data rates through extensive simulation experiments.
